Transformer Performance Tester
JYV-40 - Kingrun Instrument Co., Ltd. (KRI)
JYV-40 segment voltage test equipment is made up of constant current source, voltage-checking circuit and control circuit. The output current is adjustable and stable. Measured voltage value can be shown by three and half digital voltmeter, it can test the DC interturn and segment voltage and also is the effective way of checking turn coil resistance equilibrium.
