Role And Classification Of Mutual Inductor
Jun 12, 2018

The transformer is used in the power system with high voltage and high current, which is transmitted to low voltage and small current two times. The measurement instrument and the relay maintenance and automatic equipment get a special transformer. It is the contact element of the primary system and the two system. The primary winding is connected to the power grid. The two windings are connected with measuring instruments and relay protection devices respectively. In cooperation with measuring instruments and measuring devices, transformers can measure the voltage, current and electrical energy of a system, and cooperate with relay protection and automatic equipment. It can form electrical maintenance and automatic control of various faults of the power grid. The function of the transformer directly affects the accuracy of the measurement and measurement of the power system and the reliability of the relay maintenance equipment.

Mutual inductor is divided into two categories: voltage transformer and current transformer.

<1) the voltage and current information of the primary system can be accurately transmitted to the two side of the equipment.

(2) the high voltage of the first system. The high current is converted to two side low voltage (standard value 100V, 100 / root three V), small current (standard value 5A, 1A). Standardizing and miniaturized the measuring, measuring instruments and relays, and reducing the insulation requirements for the two equipment.

(3) the two side equipment and the two system and the one system high voltage equipment will be well separated from the electrical system, and then ensure the safety of the two equipment and personal safety.
