Introduction of Current Transformer for Motor Test

Release time:


The current transformer for motor test can be divided into primary side tap switching or secondary side tap switching according to the range switching mode. According to the characteristics of the motor test, the transformer mainly uses the secondary side to switch the range, and the secondary side can use manual transfer switch or relay to close the circuit to switch the range, which is convenient for remote automatic measurement and simple operation and maintenance. The current transformer with a primary side tap switching range can use a three-phase cage-type no-load electric switch to switch the range, which is conducive to the realization of automatic measurement.
