Product Description

on-Line Partial Discharge Tester for cable, GIS, circuit breaker monitoring

I. Product overview    
tThis product can be widely used in the partial discharge detection of power systems, including high-voltage switchgear, ring main unit, voltage/current transformer, transformer (including dry-type transformer), GIS, overhead lines, cables and other equipment insulation state detection, through the following indicators to measure the degree of discharge of electrical equipment:
Partial Discharge Intensity Detection: The intensity of partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence by measuring the discharge signal within 1 power frequency cycle.
Partial discharge frequency detection: By measuring the discharge signal within 1 power frequency cycle, the discharge pulse is extracted and the frequency of partial discharge is characterized according to the number of discharge pulses.
