Introduction:
WRT Transformer Winding DC Low Resistance Ohmmeter is a high precision new generation product that can replace 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.
WRT Transformer Winding DC Low Resistance Ohmmeter is suitable for large-scale transformer above240MVA in temperature rising tests.
840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
Dual-channel shows the measurement data at the same time.
Each interval of 60 seconds automatically print data.
Equipped with temperature conversion software, curve waveforms.
