Tech: Oscillating Wave Test System Locates Partial Discharge Faults

The oscillating wave test system from HV Hipot Tester Electric Co., Ltd can be used to identify, evaluate, and locate partial discharge (PD) faults in a cable insulation and in joints and terminations. The system can be used for all types of MV cables. Detailed information of the operational reliability of a cable system can be determined.


· Compact PD: combination of OWTS, tan delta test and the fault location system.

· PD diagnosis under oscillating wave test voltage - electrical field distribution as in nominal service conditions.

· PD evaluation possibility and pattern recognition at nominal voltage level.

· Modern industrial PC for system control and user interface.

· Semi and fully automatic PD analyzing software for defect location with mapping feature.

· Calculation of the cable capacitance and the tan delta value of the test object from the characteristic decrease of the voltage wave shape.

· Simple to use and easy to handle menu-driven unit for operation of the test sequence.

· Compact design, low weight.
