It is suitable for evaluating the insulation quality of high voltage transformergenenratorling-distance power cable and busbar under strong interference in the field of high-voltage substation and power plant.Specially used for 110KV and above large capacity transformer and long distance power cable power system

1.Strict accordance with the safety standards for design with 5 range: 500V 1000V 2500V 5000V 10000V test up to 10TΩ.
2.This instrument has the function of automatic calibration and calibrate precision  automatly before test
3.Actual test object live voltage measurement functionmeasure leakage currentdischarge automatly.
4.automatic measure and remenber R15S、R60S 、R10min valueAutomatic display polarization index (PI) induced electric absorption test values than (DAR)and test time.
5.Anti-jamming performance is superior the interference current reaches 600 mA still ensure accuracy of test instruments.
6.Automatic discharge:quickly discharge for capacitive test object by advanced high-voltage discharge technology and real-time measurement of discharge voltage (test voltage to 0v) .
7.powered by  internal rechargeable lithium battery  or ac power supply the real ac and dc dual use does not affect the test accuracy.
8.digital displayautomatic display battery level and undervoltage alarm protection function.
9.Short circuit protection short circuit condition will not burn out the instrument
