Product Description

This device can be used for measuring water cooled generator or laboratory insulation test.


1. 32 bit micro controller, menu operation

2. Large output current (>25mA under 2500V), short circuit current>=25mA

3. safe and reliable with hv generator fully enclosed and with protective resistor inside.

4. strong anti-interference ability, can satisfy EHV substation site operation

5. auto discharge after test and real-time monitor discharge process

6. suitable for measuring insulation resistance, DAR ( R60S/R15S) and PI (R10min/R1min) of water cooled generator

7. testing voltage 2500V/5000V, can measure up to 2TΩ insulation resistance

8. auto compensation to water polarization potential, measuring being accurate even when the resistance between the base and water collecting pipe is less than 10KΩ

9. high output power, load resistance between circuit to water collecting pipe can be as low as 100kΩ (2500V)/150kΩ(5000V),insulation resistance can be low as 1MΩ(2500V)/2MΩ(5000V)

10. simulation progress bar displaying the insulation resistance value, logarithmic scale, easy to read

11. 31/2 LCD digital meter

12. it can display time (minute/second, 32 minutes a cycle), and beep every 15 seconds,

13. auto test and record value of R15S, R60S, R10min, absorptance and polarization index



Test range: 0.1 MΩ-200GΩ

Accuracy: ± (10%+ 5words)

Display: digital display plus simulation progress bar display
