digital partial discharge detector for high voltage switchgear pd test Overview
digital partial discharge detector using TEV sensor, ultrasonic sensor and broadband current transformer on-line monitoring of partial discharge in high voltage switchgear. Easy to carry, rapid measurement, strong anti-interference ability, easy to use in the field.
The configuration software is 2D 3D, time-domain graphics, statistical map, alarm history, history, pulse counting function, the software can also be a phase waveform analysis detailed, window zoom in and out freely, can also analyze the frequency spectrum of the data, spectral analysis content of discharge waveform, the more comparable discharge waveform, a comprehensive statistical analysis of test data, reduce the stability factor in test on the test results.
This instrument uses automatic or manual record to save test data and transient discharge waveform, produce test report, and provide reference for later data analysis
