Product Overview
Description
This product can be widely used in partial discharge detection of power system, including insulation state detection of high-voltage switchgear, ring network cabinet, voltage/current transformer, transformer (including dry-type transformer), GIS, overhead lines, cables and other equipment. The discharge degree of electrical and gas equipment is measured by the following indicators:
Partial discharge intensity detection: measure the discharge signal within one power frequency cycle, and characterize the partial discharge intensity according to the maximum value (dB) in the discharge pulse sequence.
Partial discharge frequency detection: measure the discharge signal within one power frequency cycle, extract the discharge pulse and characterize the frequency of partial discharge according to the number of discharge pulses.
