Effect of transformer:（互感器作用）

Power system for the transmission of electrical energy,Often use the AC voltage、Large current circuit to the power sent to the user，Can not be directly measured by instrument。Transformer.The AC voltage and current proportional to the direct measurement of the value of the instrument can be used，For directly measuring instrument ，At the same time provide power supply for relay protection and automatic device。Power system transformer is high voltage power grid、Current information is transferred to the low voltage、The two side of the small current measurement、Measurement and relay protection、A special transformer automatic device，

Contact element is a system and the two system，The primary winding is connected to the grid，The two windings are respectively and measuring instrument，Protective devices connected to each other。The transducer and the measuring instrument and measuring devices with，Voltage can be measured in a system、Current and power，Cooperating with relay protection and automatic device，Can form electrical protection for power grid fault and automatic control。Transformer performance is good or bad，Directly affects the power system measurement、The accuracy of the measurement and relay protection device reliability。
