Description
The oscillating wave test system (OWTS) is used to identify, evaluate and locate partial discharge (PD) faults in cable insulation and accessories in all types of high voltage power cables. The OWTS system can both be used for commissioning testing of newly installed cables and diagnostic testing on aged cables.
The system consists of a notebook as a control unit and the HV part. The HV part contains of a HV source with an integrated electronic switch and a resonance inductor to generate a damped AC test voltage. The HV divider and the coupling capacitor are integrated in a separate unit together with the embedded controller for the digital data acquisition and PD signal processing. The storage, analysis and evaluation of the PD signals takes place in the notebook and can be done either on site or in the office.
Features
- PD diagnosis by means of damped AC voltage (DAC)
- PD level measurement according to IEC 60270
- Adjustment features to optimize detection sensitivity
- Automatic calibration mode with joint location feature
- Real-time data processing
- Menu-driven unit to operate the test sequence
- Portable design, low weight, easy set-up on-site
