Dielectric Diagnosis and Partial Discharge Measuring System

The oscillating wave test system OWTS is used to identify, evaluate and locate partial discharge (PD) faults in a cable insulation and in joints and terminations.

The HV unit generates the attenuated oscillating frequency up to the peak v oltage of the system. An Embedded controller for the operation and the digital signal processing and storage from two 100 MHz AD converter systems is intergrated in the cylindrical housing. Transport wheels permit easy transportation. The communication to the user interface of the notebook is done by W-LAN. Optional a optical data link is possible.

The OWTS can also be coupled with a VLF System. In this case the VLF provides, controlled by the OWTS, the High Voltage supply.

Key Benefits:

PD diagnosis under oscillating wave test voltage - electrical field distribution as in nominal service conditions
PD evaluation possibility and pattern recognition at the nominal voltage level
Automatic Calibration and Joint location facility
PD level measurement according to IEC 270 at a bandwidth of 150 ... 650 kHz
Semi- and fully automatic PD analysing 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
Compact PD: combination of OWTS, vlf test unit and the fault location system Compact
