Transformer action are the following: the primary circuit of high voltage and high current becomes standard position of the secondary circuit, generally rated secondary voltage of 100V open-type transformers, rated secondary current is 5A, so that the measured meter site standardization and protection devices, as well as secondary equipment insulation level can be low-voltage design zero-sequence current transformer, thus lightweight structure, the price is cheap. All secondary equipment available low voltage, low current control cables, wiring within the screen simply a single, easy to install. At the same time, to facilitate centralized management of bamboo, it can be remotely controlled and measured. Secondary circuit is not a limit circuit. Can be Y-shaped, △ shaped or V-shaped connection, thus wiring flexibility. Meanwhile, the secondary equipment maintenance, as well as adjust the test replacement, without interrupting the operation of a system, only suitably changed secondary wiring can be realized. The secondary equipment and staff and the high-voltage part isolated and transformer secondary side are grounded, thus ensuring equipment and personal safety. Voltage transformer (Potential transformer called PT, Voltage transformer also referred VT) and the transformer is very similar export transformer, are used to convert the voltage on the line. But the purpose of converting the voltage transformer is to supply electric power, so large capacity, usually in kVA or MVA for the unit; and the purpose of converting the voltage transformer voltage is mainly used for measuring instruments and relays power supply protection device, used to measure line voltage, power and power transformers, or to protect valuable equipment lines, motors and transformers in the line fails, the voltage transformer capacity is small, usually only a few volts Ann, dozens of VA, not more than one maximum kVA.
