OWTS Cable PD Fault Locator Oscillating Wave Test System for Locating Partial Discharge Locations in Cables
* Poor installation
* Failures due to inappropriate laying
* Weak spots in cable accessories or
* Deterioration of cable insulation due to aging It allows much more than a simple go or no-go decision.
DAC testing is an advanced maintenance tool which supports asset management and grid operation as well.
* Sound withstand test method with test voltages representing operational stresses
* Sensitive PD measurement and location in complete cable systems (insulation and accessories)
* Assessment of cable aging status in comparison with other cables based on dissipation factor estimation.
On-site DAC voltage test in combination with non-destructive PD and loss factor measurements is unique and fundamental for reliable service of newly installed, repaired or service-aged cable systems.
The M30 series is an integrated partial discharge localization system, mainly used for partial discharge diagnosis of medium voltage cables. The M30 series is an integrated partial discharge localization system, mainly used for partial discharge diagnosis of medium voltage cables. The system tests a damped AC voltage (DAC) at frequencies from 20Hz to 1000Hz. The damping AC voltage generated by the system during the testing process can reach up to 30kV, and is combined with advanced system hardware and system software for diagnosis.
mainly include:
- The latest transistor technology and laser control technology, such as high voltage transistor switches;
- Electronic components, digital signal processing, such as high voltage transistor switches, high voltage sources;
- Digital signal processor and filter, data acquisition device A/D converter not less than 14Bit
- All-in-one software, compatible with data from other similar manufacturers, and automatically export reports
