Product Description

GDPD-505 Portable Partial Discharge Tester with different sensor




General introduction
GDPD-505 is a portable multi-functional PD online detector, which is suitable for transformers and GIS. 
The system includes special UHF sensors, 40kHz ultrasonic sensor, HFCT(high frequency current transformer) for GIS, special 150kHz ultrasonic sensor and HFCT for power transformers.

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 ofGIS, transformers.

Features
The main detector is portable design, robust and reliable. 
Using 14inch laptop, built-in 20Ah Li-battery. Working up to 4hours without external power supply. 
Strong anti-interference ability. Using digital filtering technology, effectively eliminate field interference.
Multichannel data collection. Comprehensive analysis of electromagnetic wave and ultrasonic wave generated by partial discharge.
Easy wiring. BNC port for sensors and detector.
Strong software functions. With PD measurement and analysis, Measurement and analysis of PD repeat discharge times "n", anti-fixed interference, anti-dynamic interference, display mode of ellipse, straight line and sine wave can be selected.
The discharge result is accorded with IEC60720 standard. The display value unit is pc and mV.
