GDPD-505 is a portable multi-functional PD online detector, which is suitable for testing transformers, GIS, switch cabinet, power cables, lightning arrester and CT/PTs.
The system includes detector, software, HFCT(high frequency current transformer), calibration pulse generator, 40kHz ultrasonic sensor, 150kHz ultrasonic sensor, UHF sensors, TEV sensors, Acoustoelectric sensors and some connection cables.
It uses pulse current, ultrasonic and UHF technology, to detect and analyze HF electromagnetic signals and ultrasonic signals of internal transformers and GIS, so that to detect and evaluate the running status of GIS, transformers.
