Product Description

Ultrasonic flaw detector/Switchgear partial discharge detector tester

This product can be applied to the local discharge detection of power system, including high-voltage switch cabinet, ring network cabinet, voltage/current transformer, transformer (including dry transformer), GIS, overhead lines, cables and other equipment insulation state detection, through the following indicators to measure the discharge degree of electrical equipment:

Partial discharge intensity detection: By measuring the discharge signal in one power frequency cycle, the intensity of partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence.

Partial discharge frequency detection: By measuring the discharge signal in one power frequency cycle, the discharge pulse is extracted and the frequency of partial discharge is characterized according to the number of discharge pulses.
