The working principle of current transformer and the transformer is the same. Both work with the principle of the magnetic effect of current. The role of the transformer is to convert one level of voltage into another level of the same frequency voltage. It only has the completed voltage The conversion of output cannot complete the conversion of output power. The transformer is divided into a voltage transformer and a current transformer.

The role of the voltage transformer is to supply voltages such as detection instruments and relays, and then accurately reflect the various operating conditions of the primary electrical system. Isolate the secondary electrical systems such as testing instruments and relays from the primary electrical system to ensure the safety of workers and secondary machinery and equipment, and convert the high voltage of the primary electrical system into a low voltage value of the same standard (100 V, 100 /1.732 volts, 100 /3 volts).

The role of power transformers is basically the same as that of voltage transformers. The difference is that current transformers convert a large current in the electrical system into a standard 5 A or 1 A. Supply the relay to detect the current coil of the instrument.
