Current Voltage Transformer Coil Tester for Electrical Applications

Product Description

WRT Micro Ohm Meter Current Voltage Transformer Coil Loop DC Winding Resistance Tester

Product Description

 

WRT 20A Micro Ohm Meter Current Voltage Transformer Coil Loop DC Winding Resistance Tester is a high-precision new-generation product that can replace the DC Wheatstone Bridge and double-arm Bridge.

It adopts the advanced starting power constant current source technology, uses four digit and half LCD display value and three digit and half LCD displays the ambient temperature or test current value, it overcomes the shortcoming that the LED display ambient value reading of other similar product is not convenient to read under the sun, at the same time it has the automatic arc extinguishing function.

It is an ideal equipment for measuring transformer winding and large power output inductor equipment.
