GTPD-92C Patrol UHF PD tester uses ultra high frequency (UHF) measurement and ultrasonic (US) measurement methods to detect GIS faults. The instrument has multiple functions of PD analysis.
1. Small size, light weight, easy to carry and convenient for field use.
2. Adopting automatic gain control, strong anti-interference ability.
3. UHF measurement adopts waveform mode, statistical mode (peak chart, PRPD chart, HRPS chart), pulse mode.
4. Ultrasonic (US) measurement adopts waveform mode, continuous mode and phase mode.
5. Time domain waveform multi-wave display mode can accurately judge the interference and discharge.
6. The software provides an expert library and an intelligent diagnosis system to accurately determine discharge types.
7. By measuring the pressure of the ultrasonic signal to speculate the discharge intensity, the discharge position can be accurately determined.
8. With data preservation function, data can be reviewed.
9. The inspection data can be exported to the computer through SD card or U disk, so as to complete report.
