  • INQUIRY

GTPD-92B Patrol TEV PD tester uses transient earth voltage (TEV) measurement and ultrasonic (US) measurement methods to detect switch cabinet faults. The detector can be used for multi-signal periodic observation of measurement, frequency identification of discharge, and analysis of various modes to clearly judge whether the switch cabinet is faulty or not.

Functions and Feature

1. Small size, light weight, easy to carry and convenient for field use.

2. Adopting automatic gain control, strong anti-interference ability.

3. TEV 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. With data preservation function, data can be reviewed.

8. The inspection data can be exported to the computer through SD card or U disk, so as to complete report.

9. Combining the TEV sensor and ultrasonic sensor (contact type) detection methods together.
