Description:

200KV DC Hipot tester, model DP200 is a high-performance, portable test system which is used to evaluate the insulation situation of different electrical equipment, such as power cables, surge arresters , motor and generators, both DC Hipot and leakage current.

Standard conformed to：

DL/T848.1-2004,General technical specification of high voltage test devices Part 1:High voltage DC generator.

Applications： 

200KV DC Hipot tester, model DP200 main applications as below

Together its current-limiting resistor, DP200KV/5mA could be used to perform 110KV and below power cables test. Both acceptance test and preventive test. DC proof and DC leakage;

Table 1. DC Hipot test voltage and time for different power cables

To test 110KV system voltage gapless MO surge arresters, its 1mA reference voltage is 145KV; Both 1mA reference voltage and the leakage current at 0.75UDC1mA; The acceptance criterion＜50μA;

All kinds of motor and generators. Once it is used to test water-cooled generators, the cooled water should be discharged and dried thoroughly. Both DC Hipot and Leakage current;
