GTPD-4C partial discharge comprehensive tester is the new generation of digital PD measurement and analysis instrument. The instrument has a strong ability of comprehensive analysis of partial discharge and detection of partial discharge in small signal and strong interference environment. With different accessories, it can measure and locate the partial discharge in any high voltage electrical equipment. It can realize testing the transformer partial discharge by applying the voltage on the three phases simultaneously.

Functions and Feature

1. Multi signal channel, desktop, TFT liquid crystal display, reliable system, low failure rate, strong anti- interference ability.

2. It integrates functions of measurement, diagnosis, location and on-line monitoring.

3. The location of fault position can be achieved by electro-acoustic and acoustic-sound.

4. According to the testing process, the test report can be generated automatically and the report can be read and printed.

5. The replay function can restore the saved data file to the waveform displayed on the screen.

6. Four channels electrical signal and four channels optical signal input port can simultaneously realize the measurement and analysis of multi-channel partial discharge signal.
