RS-9003 Partial Discharge Inspection Device for Switchgear, Cable, Transformer and GIS
Portable PD tester is used for on-line detection and location of partial discharge of HV equipment, which is designed based on our many years experiences in the partial discharge measuring fields.
The system is equipped with composite TEV sensors, ultrahigh frequency sensors, High-frequency current transformers and high sensitivity ultrasonic sensors to collect partial discharge signals at high voltage equipment. The system adopts multilevel detect frequency reduction techniques to reduce the discharge frequency of the signals, meantime using high-speed AD conversion circuit to complete the signal digitization, also by using digital signal processing, adaptive filtering interference signal processing methods to ensure the reliability of the testing data. By collecting different signals produced from the partial discharge in different high equipment, the equipment operation status can be detected rapidly. The tester can be installed for detection with equipment operation and without any effect to the equipment operation. This will help the workers to make evaluation timely for the switchgear cabinet operation status, and thus greatly improve the equipment operation reliability, safety and effectiveness.
The Portable PD tester consists of main tester, PD testing software, composite TEV sensors, ultrasonic sensors, high-frequency current transformer, ultrahigh frequency sensor and connecting cables
