What Is The Function Of Voltage Transformer And Current Transformer?
Mar 09, 2018

What is the function of voltage transformer and current transformer?

Transformer for voltage transformer and current transformer two, its main function has: voltage and current information of a system accurately transferred to the two side related equipment; high voltage and large current transform a system for low voltage side of two (standard), small electric flow (standard), the standard device of the measuring instruments and relays and miniaturization, and reduces the insulation requirements of the two equipment; the two side equipment and two system and a system of high voltage equipment in electrical isolation well, so as to ensure the equipment and two people the safety.

Two are all special transformers! Commonly used in instrument signal acquisition,

Voltage transformer (PT) is used to convert voltage. It is usually converted to conventional voltage, such as 110KV, 10KV, for ordinary instruments, 380V, 220V, so that the instrument can be displayed. The voltage transformer can be open for two times, but it can not short circuit.

The current transformer (CT) converts large current signals (hundreds of amperes and thousands of Amperes) into small currents that are easy to use by current instruments.

The current transformer can be short circuited two times, but it is not allowed to open the road.

In the new installation of PT, CT transport or replacement of PT, CT two cables, the need to check the correctness of the PT, CT wiring, that is the same name.
