Product Feature And Application
1. With strong anti-electric field interference ability up to 2mA (50Hz), it is suitable for a 500kV substation without dismantling wire to test the insulation resistance of a 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 ~ 1999MΩ. With high-resolution, having accurate readings.
4. Wide voltage range: 0.5kV, 1kV, 2.5kV, 5kV, 10kV, 20 kV, you can smoothly adjust voltage from 0V to the desired value.
5. With the timekeeping function, remind users to record, and analyze the absorptance and polarization index of the measured target.
