Product Description

20A Single & Three Phase Coil DC Resistance Tester transformer ohm meter

• INTRODUCTION:

It is applied to measure the DC resistance of inductance circuit such as power transformer coil, current transformer coil and so on.

Also the tester could be applied to measure the cable resistance in 4-wire mode.

• FEATURES:

1. It is suitable for large-scale transformer above 240MVA in temperature rising tests.
2. 840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
3. Dual-channel shows the measurement data at the same time.
4. Each interval of 60 seconds automatically print data.
5. Equipped with temperature conversion software, curve waveforms.
