 +            Power Flow Overloaded Network - Bloomberg</​a></​dt>​
 +        <​dd>​The Czech power grid in 2011 was repeatedly and &#​8220;​more
 +          frequently&#​8221;​ overloaded with unscheduled flows of electricity
 +          caused by renewable energy from Germany, jeopardizing the
 +          security of the network, grid operator CEPS said. The most
 +          critical situation occurred in the period between Nov. 25 and
 +          Dec. 16 when unscheduled power flows amounted to 3,500
 +          megawatts while the usual value is about 1,000 megawatts, the
 +          Czech operator said in a statement today on its website. The
 +          near-emergency situation in the network was mainly caused by
 +          excessive power output from German wind farms on windy days.
 +          The shutdown of German nuclear plants, the rise of installed
 +          capacity in photovoltaic power plants in Germany and intensive
 +          power trading on spot markets also played a part in the
 +          network overloads, CEPS (PCZPBL01) said. CEPS has implemented
 +          measures to identify and predict such situations and said the
 +          risk of the recurrence of such situations in the future still
 +          persists and the transmission networks in the region must be
 +          reinforced as quickly as possible, it said. The country may
 +          have to install transformers at the borders to protect the
 +          grid at a cost of 2 billion koruna ($99 million), CEPS chief
 +          Vladimir Tosovsky told reporters at a press conference in
 +          Prague today, newswire CTK reported. CEPS already plans to
 +          invest 3.5 billion koruna in the network in 2012, the newswire
 +          reported.</​dd>​

 +          permissible to land the equipment grounding conductors on the
 +          neutral bus bar with the grounded (neutral) conductors, or am
 +          I required to set a ground bar for the equipment grounding
 +          conductors? A1: Equipment grounding conductors can terminate
 +          on the same terminal bar with the grounded (neutral)
 +          conductors, but this is only permitted if the panelboard is
 +          rated service equipment and it is used as service equipment in
 +          accordance with 230.71(A). However, each grounded (neutral)
 +          conductor must terminate within the panelboard in an
 +          individual terminal [408.21]. // Grounding Remote Building and

 +          during normal operation (like resistors in parallel). Is this
 +          a trivial concern? Do you know of any problems that can arise
 +          from such a situation such as GFI relays in the main service?

 +        <​dd>​Although the National Electrical Code doesn&#​8217;​t require a
 +          specific color code for ungrounded conductors, electricians
 +          often use the following color system for power and lighting
 +          conductor identification:​ &#8226; 120/240V, single-phase wiring &#8212;
 +          black, red and white &#8226; 120/208V, three-phase wiring &#8212; black,
 +          red, blue and white &#8226; 120/240V, three-phase wiring &#8212; black,
 +          orange, blue and white &#8226; 277/480V, three-phase wiring &#8212; brown,
 +          orange, yellow and gray; or, brown, purple, yellow and gray On
 +          the grounded side for neutrals, the wires have to be white or
 +          gray. Buc prefers white at 120/240 (208) and gray for 277/480
 +          circuits. Green or bare wire is always the grounding
 +          conductor. Personally, Buc specifies the latter 277/480 color
 +          grouping; that removes the &#​8220;​orange&#​8221;​ wire color and any
 +          confusion. Why? Orange is the only specified ungrounded
 +          conductor and marks the &#​8220;​wild leg&#​8221;​ of a 120/240 center-tapped
 +          neutral delta configuration. For those unfamiliar: In wild leg
 +          configuration,​ the two end phases on the center-tapped winding
 +          provide 120 volts to neutral, but on the wild leg you will
 +          find nearly 208 volts to the neutral. If you see an orange
 +          wire in a panel, alarm bells of caution should go off in your
 +          head. You don&#​8217;​t want to wire a 120 VAC outlet across the wild
 +          208 volt phase.</​dd>​

 +        <​dd>​http://​www.webcitation.org/​6DGvahbT9 /// It&#​8217;​s the end of the
 +          world as we know it. That&#​8217;​s what the U.S. wind power industry
 +          is saying to itself these days. And they aren&#​8217;​t talking about
 +          some Mayan doomsday nonsense. On Jan. 1 the federal production
 +          tax credit on wind investments expires. For the past 20 years
 +          the credit has offset about 30% of the cost of building wind
 +          turbines. Add to that the &#​8220;​renewable portfolio standards&#​8221;​ for
 +          green energy mandated by 29 states, and as a result we&#​8217;​ve seen
 +          wind farms spring up across the country. Since 2007 nearly 40%
 +          of all the new electricity capacity built in this country has
 +          been wind. Wind now generates roughly 3.5% of U.S.
 +          electricity. Don&#​8217;​t expect wind&#​8217;​s share to climb beyond that
 +          level any time soon. The end of the tax credit could very well
 +          mean the end of the wind industry. According to the federal
 +          Energy Information Administration,​ the &#​8220;​levelized cost&#​8221;​ of new
 +          wind power (including capital and operating costs) is 8.2
 +          cents per kWh. Advanced clean-coal plants cost about 11 cents
 +          per kWh, the same as nuclear. But advanced natural gas-burning
 +          plants come in at just 6.3 cents per kWh. But it could be
 +          getting a lot worse for wind. A fascinating new report by
 +          George Taylor and Tom Tanton at the American Tradition
 +          Institute called &#​8220;​The Hidden Costs of Wind Electricity&#​8221;​
 +          asserts that the cost of wind power is significantly
 +          understated by the EIA&#​8217;​s numbers. In fact, says Taylor,
 +          generating electricity from wind costs triple what it does

 +        <​dd>​http://​www.webcitation.org/​5u1abZrFW // The term "​Ufer"​
 +          grounding is named after a consultant working for the US Army
 +          during World War II. The technique Mr. Ufer came up with was
 +          necessary because the site needing grounding had no
 +          underground water table and little rainfall. The desert site
 +          was a series of bomb storage vaults in the area of Flagstaff,
 +          Arizona. The principle of the Ufer ground is simple, it is
 +          very effective and inexpensive to install during new
 +          construction. The Ufer ground takes advantage of concrete&#​8217;​s
 +          properties to good advantage. Concrete absorbs moisture
 +          quickly and looses moisture very slowly. The mineral
 +          properties of concrete (lime and others) and their inherent pH
 +          means concrete has a supply of ions to conduct current. The
 +          soil around concrete becomes "​doped"​ by the concrete, as a
 +          result, the pH of the soil rises and reduces what would
 +          normally be 1000 ohm meter soil conditions (hard to get a good
 +          ground). The moisture present, (concrete gives up moisture
 +          very slowly), in combination with the "​doped"​ soil, make a
 +          good conductor for electrical energy or lightning currents.
 +          Ufer techniques are used in building footers, concrete floors,
 +          radio and television towers, tower guy wire anchors, light
 +          poles, etc. Copper wire does not function well as a "​Ufer"​
 +          ground due to the pH factor of concrete (+7pH is common). The
 +          use of steel reinforcement as a "​Ufer"​ ground works well and
 +          concrete does not chip or flake as has been found with copper.
 +          The use of copper wire tied to the reinforcement rods outside
 +          the concrete shows none of these problems.</​dd>​

 +        <​dd>​Over the past few months, the Government of Liberia (GOL)

 +          keep a hydro operating right here in Liberia and he is in
 +          charge of ensuring that Firestone Liberia meets its power
 +          supply. The individual is Patrick Brown. With our government
 +          full support, Patrick can restore our hydro. GOL should
 +          negotiate with Firestone Liberia and lure him. He has what it
 +          takes to do the job. Patrick manages a team of Liberians
 +          operating and maintaining Firestone Liberia hydro. This
 +          brother worked for LEC for many years at Mount Coffee. He
 +          knows the facility well. I believe GOL should use him and give

 +          from a GE transformer connections book copy righted in 1970.
 +          Y-Y connected transformers,​ excepting three-phase core-type
 +          units, are not capable of supplying an appreciable
 +          single-phase load from line to neutral without a serious shift
 +          in the position of the neutral, owing to the fact that the
 +          corresponding primary currents of such loads, flowing through
 +          the primaries of the unloaded phases, magnetize them. This
 +          statement is primarily true for Y-Y connected single-phase
 +          units and shell-type three-phase units. Core-type units,
 +          however, may, on account of the interlinking of the magnetic
 +          fluxes in the three legs, give tolerably good results under
 +          conditions of single-phase loads from line to neutral or
 +          unbalanced electrostatic charging currents. // The wye-wye- is
 +          used under the same condition and to supply the same mixed
 +          distribution loads as the delta-wye connection. The division
 +          of load between transformers is also similar to t hat of the
 +          delta-wye. CARE SHOULD BE EXERCISED IN MAKING THE WYE-WYE
 +          CONNECTION TO MAKE SURE THAT A WIRE CONNECTS PRIMARY BANK AND
 +          PRIMARY CIRCUIT NEUTRALS. iF NOT, TWO PRIMARY WINDINGS WILL BE
 +          IN SERIES BETWEEN EACH TWO PHASE WIRES. Current into a
 +          transformer from its phase wire can return only through the
 +          other two phase since there is no neutral return. Thus , the
 +          wye-wye without connected primary bank and primary source
 +          neutrals can operate satisfactorily only when the load is
 +          EXACTLY balanced between each phase and neutral on the
 +          secondary with equal phase to neutral voltages. Only then will
 +          the vector sum of the phase currents add up to zero at the

 +          Nuclear power generation using U.S. technology is not only

 +          Since Dr. Beckman'​s book was published it has been shown that

 +          gases and scrubber sludge to power a nuclear power plant
 +          larger than the coal powered plant. One of the few significant
 +          hazards of nuclear power is the release of radioactivity. Most
 +          coal plants release too much radioactivity to operate if they
 +          were regulated by the NRC. U.S. background radiation is about
 +          250 millirems per year (some locations in other countries have
 +          levels 20 times higher). To this, nuclear power plants add

 +          power plant adds about 1/100 as much radiation as 1 old color
 +          TV. Grand Central station in NY could not be licensed as a
 +          nuclear reactor even without any fuel because its granite
 +          blocks emit too much radiation. // In 1973 calculations show

 +        <​dd>​http://​www.webcitation.org/​6FSRc1hhk /// During the 1960s,
 +          Stanley Consultants was selected by the Liberia Electricity
 +          Corporation (LEC) as the design engineer for the new Mount
 +          Coffee 64 MW hydropower project on the St. Paul River in
 +          Liberia, West Africa. Upon completion, it was named the Walter
 +          F. Walker Hydro Dam and contained four vertical hydroelectric
 +          generating units, 3 earth-filled dam sections, 10 flood
 +          control gates, and a 69 kV substation and transmission line.
 +          This facility became the country'​s largest source of
 +          electricity. This facility operated successfully until 1990
 +          when the National Patriotic Front of Liberia took control of
 +          the project site during the First Liberian Civil War and did
 +          not permit LEC to open the tainter gates during high water
 +          events. Eventually, the earth-filled dam was overtopped and
 +          destroyed. Since then, the powerhouse has been vandalized,
 +          looted and all mechanical and electrical systems have been
 +          destroyed, leaving only the concrete substructure,​
 +          superstructure and steel penstocks. In 2007, Stanley
 +          Consultants was again retained by LEC to determine the
 +          feasibility of restoring the facility and to research the
 +          project'​s potential environmental and socioeconomic benefits.
 +          A damage assessment study and field observations were
 +          performed on the dam in the areas of civil, geotechnical,​
 +          hydro-mechanical,​ and electrical engineering. After the
 +          investigations,​ a comprehensive report outlined rehabilitation
 +          requirements and the engineering work required to restore the
 +          plant. In addition%2</​dd>​

 +        <​dd>​When two &#​8220;​isolated&#​8221;​ grounding systems are horizontally
 +          separated by only 10 ft of earth, they are not electrically
 +          insulated from each other. This medium-to-high impedance can
 +          lead to a possibly harmful potential difference between the
 +          grounding systems and the distribution system&#​8217;​s neutral and
 +          grounding conductors. In B.T.&#​8217;​s example, there are two
 +          grounding connections of the system&#​8217;​s grounded conductor
 +          (neutral): one at the transformer and the other at the
 +          building&#​8217;​s service disconnect. Each is connected to its
 +          respective ground electrode. However, a reduced amount of
 +          objectionable current will still flow across the earth gap,
 +          separating the two grounding systems. Small voltages thus
 +          generated are more than enough to create possible destructive
 +          interference on digital control and communications networks
 +          and computer-operated devices. Preventing this requires one
 +          connection between the power system&#​8217;​s grounded conductor and
 +          just one of the grounding systems, with both grounding systems
 +          then directly connecting together. This is permitted by Sec.
 +          250-21 of the NEC. &#​8212;​F.M.P.</​dd>​

 +          provided conceptual design and feasibility study to redevelop
 +          hydroelectric power and construct an upstream storage
 +          reservoir. Located on the St. Paul River, Mt. Coffee formerly
 +          generated 64 MW of power. Originally designed by Stanley
 +          Consultants,​ and constructed in the 1960s, it was Liberia&#​8217;​s
 +          largest source of electricity and vital in their plans for
 +          reconstruction and restoring commercial productivity. The
 +          project consists of a 3-km-long, earth-filled dam that diverts
 +          water to the intake structure. Penstocks then deliver the
 +          water to the powerhouse containing four vertical Kaplan units.
 +          The water is then returned to the river by a tailrace canal.
 +          The earth-filled dam was breached when LEC personnel were not
 +          allowed to raise the ten tainter gates that regulate the
 +          reservoir&#​8217;​s level. Left unraised during the rainy season, the
 +          gates caused water to eventually crest the earth-filled dam,
 +          creating a wide breach. As a result, the reservoir was drained
 +          and the intake is currently above the water. Water now
 +          bypasses the powerhouse, leaving the turbines dry. Subsequent
 +          vandalism and looting removed virtually all of the mechanical,
 +          electrical, and control systems from the powerhouse. The LEC
 +          retained Stanley Consultants to prepare an updated feasibility
 +          study for the redevelopment of hydropower at Mt. Coffee via
 +          funding from the United States Trade &amp; Development Agency.
 +          The study included conceptual designs, cost estimates, energy
 +          generation analysis, environmental review, and comprehensive

 +          "Watts up? PRO" has a USB interface, provides an integrated
 +          LCD for also monitoring the power consumption and other data
 +          that can be toggled via two buttons, and accepts any US power

 +          drop in the bucket. All of Google, all its servers and
 +          campuses and everything, require about 260 megawatts of
 +          electricity on a continuous basis, as of 2011. The US has
 +          about 1,000 gigawatts of capacity, or 1,000,000 megawatts. So,
 +          to put it mildly, I am sanguine about the electrical
 +          consumption of our computing infrastructure. But, according to
 +          a new report from the University of Melbourne'​s Centre for
 +          Energy Efficient Telecommunications,​ the wireless networks
 +          that let our devices tap into those data centers might turn
 +          out to be another story. In a new whitepaper, the CEET
 +          estimates that when we use wireless devices to access cloud
 +          services, 90 percent of the electrical consumption of that
 +          system is eaten up by the network'​s infrastructure,​ not the
 +          servers or phones.. The data centers themselves use one-tenth
 +          that amount of electricity. Worse, cloud services accessed
 +          wirelessly will continue to explode, leading to a ballooning
 +          electrical load as well. By 2015, they estimate this system
 +          could eat up between 32 and 43 million megawatt hours. In
 +          2012, the figure was only 9 million megawatt hours.</​dd>​

 +            Million for Hydro - Liberia Begins Borrowing Again</​a></​dt>​
 +        <​dd>​Finance Minister Amara Konneh Thursday (Jan 24) disclosed in
 +          Monrovia that the Government of Liberia and the European
 +          Investment Bank have completed the signing of a loan deal
 +          worth US$65 million to finance the Mount Coffee Hydro. Liberia
 +          is expected to pay back the money in 20 years at the interest
 +          rate of 1.4 percent, meaning the country will have to pay
 +          about US$73 million. Liberia only three years ago graduated
 +          from a mammoth debt burden of at least US$5 billion, an amount
 +          the country would never pay back in generations. Konneh said
 +          the loan will enable government starts the renovation process
 +          of the Mount Coffee Hydro which was destroyed more than 20
 +          years ago as result of the Liberian civil war. The hydro
 +          powered the capital and its environs, but was systematically
 +          looted during the war years. According to Konneh, a total of
 +          US$200 million is needed to complete the renovation work on
 +          the Hydro. In the same vein, he said Germany and Norway will
 +          give to Liberia in grant the amount of US$35 million and US$75
 +          million respectively as support to rebuild the Hydro, while
 +          Liberia will make an annual contribution of US$15 million
 +          towards the project. Konneh noted that the Hydro, when
 +          rebuilt, will produce about 80 megawatt of electricity,​
 +          something he said will be bigger than 20 [64] megawatts it
 +          produced prior to its destruction. // The Mount Coffee Hydro
 +          is expected to be completed in three years. It is also
 +          expected by President Ellen Johnson Sirleaf that the hydro
 +          will be officially turned on December 20, 2015.</​dd>​

 +        <​dd>​This superb book shows the extreme folly of relying on wind
 +          power for reliable electricity supply. In November 2008, the
 +          Minister for Energy and Climate Change said that gas-fired and
 +          coal-fired electricity cost &​pound;​50 per megawatt hour (MWh)
 +          to generate and nuclear power cost &​pound;​38. By contrast,
 +          offshore wind cost &​pound;​92,​ onshore wind &​pound;​72. To keep
 +          the uneconomic option of wind power alive, the government has
 +          made us all pay huge hidden subsidies, through our electricity
 +          bills, to wind power companies. As the 2003 Energy White Paper
 +          admitted, "We have ... introduced a Renewables Obligation for
 +          England and Wales in April 2002. This will incentivize
 +          generators to supply progressively higher levels of renewable
 +          energy over time. The cost is met through higher prices to
 +          consumers. ... By 2010, it is estimated that this support and
 +          Climate Change Levy exemption will be worth around &​pound;​1
 +          billion a year to the UK renewables industry."​ Yet by 2007,
 +          Britain'​s 2,400 wind turbines generated just 1.3 per cent of
 +          our electricity,​ and even this paltry supply was not reliable.
 +          The 2008 House of Lords Select Committee on The Economics of
 +          Renewable Energy said, "To make up for its intermittency ...
 +          back-up conventional plant will be essential to guarantee
 +          supply when required, to compensate for wind's very low
 +          capacity credit. Wind generation should be viewed largely as
 +          additional capacity to that which will need to be provided, in
 +          any event, by more reliable means; and the evidence suggests
 +          that its full costs, although declining over time, remain
 +          significantly higher than those of conventional or nuclear

 +        <dd>f a proposal by the National Electric Reliability
 +          Corporation (NERC) is approved, the vibrating reed meter may
 +          be making a comeback. While utility companies have prided
 +          themselves on maintaining accuracy, NERC is proposing a
 +          year-long experiment to allow the frequency to drift, and see
 +          if any problems result. It says the upside of looser
 +          tolerances would be a more reliable grid and reduced operating
 +          costs to the utilities. At the heart of the matter is a Time
 +          Error Correction (TEC). As the line frequency drifts, the
 +          electric companies intentionally create an &#​8220;​error&#​8221;​ in the
 +          opposite direction. But here&#​8217;​s where it gets complicated.
 +          Since most electric power producers are also connected to
 +          other electric power producers, they all have to make a TEC at
 +          the same time. Thus, everyone agrees to NOT try to achieve the
 +          normal goal of sixty cycles per second. Instead, they all
 +          generate a little more or a little less than the load demanded
 +          by their customers to correct the time error. The NERC
 +          estimates that with the proposed changes, fluctuations might
 +          be greater on the East Coast, with clocks running up to 20
 +          minutes fast. On the West Coast, they would only gain about 8

 +        <​dd>​This meter is monitoring the power balance of the UK
 +          electricity grid. If the needle is too far to the left, it
 +          means more generation is needed to meet demand. The meter
 +          actually shows the grid's "​frequency",​ which is related to the
 +          speed of rotation of generators all over the country. When
 +          there is too little power available, the whole grid "slows
 +          down" and the needle moves to the left. Why is this important?
 +          It is important because it is possible to measure this signal
 +          from any power outlet in the country. This means that it is
 +          possible to design electrical appliances that know the current
 +          imbalance on the grid. This is what dynamic demand control is
 +          about. The device to measure grid frequency is very simple.
 +          Here at Dynamic Demand, we built (at very little cost) a
 +          device that continuously monitors the frequency on the
 +          electricity grid and updates this website with real-time data.
 +          Dynamic demand appliances would react to this very same
 +          signal. When the needle is to the left, they would be more
 +          likely to switch off, reducing the load on the grid and
 +          helping to restore the balance. When the needle is to the
 +          right, they would be more likely switch on, using up the
 +          excess power. Millions of such devices acting together would
 +          act like a huge, fast-reacting back-up system.</​dd>​

 +        <​dd>​Although the National Electrical Code doesn&#​8217;​t require a
 +          specific color code for ungrounded conductors, electricians
 +          often use the following color system for power and lighting
 +          conductor identification:​ &#8226; 120/240V, single-phase wiring &#8212;
 +          black, red and white &#8226; 120/208V, three-phase wiring &#8212; black,
 +          red, blue and white &#8226; 120/240V, three-phase wiring &#8212; black,
 +          orange, blue and white &#8226; 277/480V, three-phase wiring &#8212; brown,
 +          orange, yellow and gray; or, brown, purple, yellow and gray On
 +          the grounded side for neutrals, the wires have to be white or
 +          gray. Buc prefers white at 120/240 (208) and gray for 277/480
 +          circuits. Green or bare wire is always the grounding
 +          conductor. Personally, Buc specifies the latter 277/480 color
 +          grouping; that removes the &#​8220;​orange&#​8221;​ wire color and any
 +          confusion. Why? Orange is the only specified ungrounded
 +          conductor and marks the &#​8220;​wild leg&#​8221;​ of a 120/240 center-tapped
 +          neutral delta configuration. For those unfamiliar: In wild leg
 +          configuration,​ the two end phases on the center-tapped winding
 +          provide 120 volts to neutral, but on the wild leg you will
 +          find nearly 208 volts to the neutral. If you see an orange
 +          wire in a panel, alarm bells of caution should go off in your
 +          head. You don&#​8217;​t want to wire a 120 VAC outlet across the wild
 +          208 volt phase.</​dd>​

 +          some 12 miles, and up to picturesque sandstone bluffs. Tommy
 +          Bolack has been collecting artifacts representing electric

 +          over thirty years. Opened to the public in 1990, the 15,000
 +          square foot exhibit area and two acres outside, display many
 +          aspects of industrial development. The largest standing
 +          display of slate and marble switchboard from nine power plants
 +          flank the north wall and represent the period from 1990 to
 +          1920. The craftsmanship and ornate nature of electric meters,
 +          relays and generators have stood the test of time. Glass
 +          insulators now stand as objects of beauty along with massive
 +          generator engines. Many items are displayed so that "​inside

 +            SparkFun Electronics</​a></​dt>​
 +        <​dd>​We are constantly pushing ourselves for better printed
 +          circuit boards (PCB). One thing we've learned is that PCB fab
 +          houses (such as Advanced Circuits, BatchPCB, PCB123, Gold
 +          Phoenix, Bare Bones PCB, anyone really) have a very hard job
 +          to do. Creating a PCB is not an easy task and there are many
 +          ways for a fab house to mess it up. Unfortunately,​ fab houses
 +          tend to spend less time on prototypes than on production runs.
 +          Therefore, we try to design products and PCBs for
 +          '​manufacturability'​. This tutorial will show you how to
 +          minimize the number of ways the fab house can screw up a PCB.
 +          We've messed up piles of PCBs over the years. We want to share
 +          with you some of the DFM (design for manufacture) rules and
 +          tricks and tips we've learned to get a good PCB, every time.
 +          If you're creating a prototype PCB, we highly recommend you
 +          use these rules to increase the chances that your proto will
 +          work!</​dd>​

 +          Harrison For his first birthday, Harrison&#​8217;​s Mom wanted to give
 +          him something really special. Not just an ordinary toy for a
 +          one year old, but something strange and wonderful, tactile,
 +          interactive,​ unique. Thus was born the idea of an &#​8220;​electric
 +          box&#​8221;,​ an electronic contraption full of switches, lights,
 +          buttons, knobs, levers, and sounds. An elite task force was
 +          assembled to create this special gift, codenamed &#​8220;​Harrison&#​8217;​s
 +          Box&#​8221;​. The team consisted of Grandpa, the Woodworker, Jeff
 +          (alias mightyohm) the Engineer, and Kylie, the Project
 +          Manager. Upon defining the project, we immediately jumped into
 +          phase one, Procrastination. Deliverables were met, and as the
 +          birthday loomed closer, we eased into phase two, Git &#​8216;​er&#​8217;​
 +          Done. Supplies and materials were ordered, wood chips started
 +          flying, and soldering irons blazed. A short time later, the
 +          front panel was realized:</​dd>​

 +          Series - The Navy Electricity and Electronics Training Series
 +          (NEETS) was developed for use by personnel in many electrical

 +          advice of, senior technicians in these ratings, this series
 +          provides beginners with fundamental electrical and electronic
 +          concepts through self-study. The presentation of this series
 +          is not oriented to any specific rating structure, but is
 +          divided into modules containing related information organized
 +          into traditional paths of instruction. The series is designed
 +          to give small amounts of information that can be easily
 +          digested before advancing further into the more complex
 +          material. For a student just becoming acquainted with
 +          electricity or electronics,​ it is highly recommended that the
 +          modules be studied in their suggested sequence. While there is
 +          a listing of NEETS by module title, the following brief

 +        <​dd>​If you service RF amplifier modules as used in most of
 +          today&#​8217;​s solid-state AM and FM transmitters,​ you will come to
 +          know that sometimes a MOSFET doesn&#​8217;​t blow up when it fails.
 +          Over time, Frank began to recognize that the &#​8220;​gate&#​8221;​ junction
 +          of a MOSFET could become &#​8220;​leaky&#​8221;​ &#8212; still working but with
 +          degraded performance. However, a &#​8220;​leaky&#​8221;​ gate can be tricky to
 +          diagnose. Some repairs are akin to &#​8220;​throwing the baby out with
 +          the bathwater&#​8221;​ in that some individuals will simply replace
 +          all of the MOSFETs. Good (and expensive) MOSFETs end up being
 +          thrown away. Frank doesn&#​8217;​t like using this &#​8220;​shotgun approach&#​8221;​
 +          when doing repairs, given the cost of several hundred dollars
 +          each. It&#​8217;​s also a personal thing for him to not waste. Frank&#​8217;​s
 +          simple project will give you a method to verify the &#​8220;​usable&#​8221;​
 +          performance of the RF MOSFET in question. Fig. 4: Brads and
 +          buss wire serve as solder points for the components. You
 +          likely have all of the parts somewhere in your shop. If you
 +          don&#​8217;​t,​ a visit to your parts store will produce everything
 +          you&#​8217;​ll need for around $10 or so. Construction can be simple.
 +          Frank used a small block of plywood and some 1-1/2-inch brass
 +          brads as the solder points, as shown in Fig. 2. The resistor
 +          values are on the schematic in Fig. 3.</​dd>​

 +          offer. The Liberia Solicitor General noted that as a

 +          Court,to peacefully and lawfully resolve the issue, but
