Energy Metering – Routine Testing of Voltage Transformers

Instrument TransformersThe Road to TestingTransformer TestingVoltage Ratings and Power QualityInstrument transformersplay a crucial role in metering and monitoring. ITs are electrical devices that operate in very high voltages or currents and transform it to lower values so that the magnitude can be measured by normal range instruments. They are mainly used for energy billing, system protection and protective relaying purposes, and load survey. There are two types of ITs: current and voltage transformers. Current transformers are used for measuring currents of high magnitude, whereas voltage transformers(potential transformers) step down voltages of high magnitudes to a lower voltage. To ensure that a transformer works efficiently, it has to be put through a number of testing procedures. A type of testing called routing testing and its sub-types are discussed further in detail.Get price

Natural gas in Israel - Wikipedia

HistoryDiscoveries in The 2000sPower StationsSee AlsoHistorically, Israel relied on external imports for meeting most of its energy needs, spending an amount equivalent to over 5% of its GDP per year in 2009 on imports of energy products. The transportation sector relies mainly on gasoline and diesel fuel, while the majority of electricity production is generated using imported coal. As of 2013, Israel was importing about 100 million barrels of oil per year. The country possesses negligible reserves of crude oil but does have abundant domestic natural gas resources which were discovered in large quantities starting in 2009, after many decades of previously unsuccessful exploration. Until the early 2000s, natural gas use in Israel was minimal. In the late 1990s, the government of Israel decided to encourage the usage of natural gas because of environmental, cost, and resource diversification reasons. At the time however, there were no domestic sources of natural gas and the expectation was that gas would be supplied from overseas in th...Get price
