In order to transmit electricity power system, often using AC voltage, high-current circuit to high voltage power transformers Tongchuan sent to the user, can not be directly measured with instruments. The role of transformer high voltage transformer Baoji is the AC voltages and currents can be reduced in proportion to the value of direct measurement instrument to facilitate direct measurement instrumentation, while providing power for the protection and automatic device. Power systems is to deliver power transformer high voltage, high current information to the low-voltage, low-current measurement of a special transformer secondary side, measuring instruments and relay protection, automatic device Xi'an high voltage transformer, is a Contact elements of the system and the secondary system, the primary winding is connected to the grid, the secondary winding respectively measuring instruments, protection devices connected to each transformer voltage and current transformers are divided into two categories. Voltage transformer can be used for voltage and power measurements in high-voltage and high-voltage power system towards. Current transformers can be used in measuring the exchange of current exchange measurements and power lines to protect electrical drag degrees. Welcome to inquire ......
