Product Introduction

The instrument is designed for HV substations and power plants to test the characteristic of large HV transformer, electric machines and appliances, remote power cable or buried cable and other electrical insulation resistance in strong interference environment. It also can be widely used for testing characteristics of insulation resistance in other area.

Product Characteristics

1. With strong anti-electric field interference ability up to 2mA (50Hz), it is suitable for 500kV substation without dismantling wire to test insulation resistance of 500kV large-scale transformer.

2. The short-circuit current of test power> 5mA, maximum up to 15mA. Be suitable for testing high capacity and high inductance.

3. Wide resistance range from 0.5MΩ ~ 200000MΩ. With high-resolution, having accurate readings.

4. Wide voltage range: 0.25kV, 0.5kV, 1kV, 2.5kV, 5kV, 10kV, 15 kV, you can smoothly adjust voltage from 0V to the desired value.

5. With timekeeping function, remind users to record, and analyze absorptance and polarization index of measured target.
