The GTPD-1 digital partial discharge tester is a mufti-function comprehensive intelligent diagnostic live inspection instrument. It can diagnose and test transformers, switches, GIS and cables on-line. It is a special instrument for testing and analyzing the insulation performance of power equipment.
Functions and Feature
1. With dual channel design, it can select special software and sensors to test the transformer, switch cabinet, GIS and cable, so as to realize professional and intelligent live detection and fault diagnosis.
2. It is easy to carry, quick to measure, strong anti- interference and convenient for field use.
3. The function of managing test file, which realizes the record, view and analyze testing data.
4. Automatic or manual recording of test data and transient discharge waveform, browsing record and playback analysis.
5. Strong anti-interference ability, which makes it be suitable for use on complex site.
6. The software has the functions of time domain graphics, 2D, 3D statistical chart, alarm in history, maximum in history, pulse counting and so on.
7. In the process of detection, the intelligent diagnosis of partial discharge is carried out automatically and in real time, and the judgment results are displayed on the screen of the instrument to help field staff to analysis partial discharge types.
8. The instrument adopts many synchronization modes, such as internal synchronization, external wired synchronization and external wireless synchronization, to facilitate field use.
