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
Ⅰ、Introduction
The HVOWTS series products have a compact structure, the system integrates a DC high-voltage output, no corona reactance, and a partial discharge synchronous measurement unit, which is compact and easy to transport. In particular, low- and medium-voltage oscillating wave equipment can be easily tested and tested in cramped spaces such as basements and switch cabinets.
The HVOWTS series is powerful, with a maximum output voltage ranging from 30 kV to 600 kV. It can provide a variety of evaluation methods for cables, such as withstand voltage testing, fault location, partial discharge diagnosis and dielectric loss detection; for power workers to manage cable assets— A comprehensive and reliable basis for decision-making.
The latest equipment software is more convenient and quick, and only one calibration is needed to complete the acquisition of all discharge parameters. The high-voltage detection process can be set according to user habits or industry standards—secondary pressure setting, without human intervention to complete the analysis while applying voltage.
