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.
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.

Time and alarm functions |
maximum value of stopwatch is 19 minutes and 59 seconds. 20 minutes for a cycle. The stopwatch will tell the time at these time points: 15 seconds 60 seconds and every 60 seconds.When telling time resistance readings hold for 3 seconds.If the measured resistance is below the lower limit of range the reading is invalid and the instrument will continuously sound to give an alarm. |
Display | three and a half bits LCD digital meter (three) respectively show test voltage test resistance test time. |
Power supply |
DC: rechargeable lithium battery DC15V power supply. With AC (50 / 60Hz) special adapter access port to charge
the battery. |
