This product is widely applicable for theater inspections in the power system, including insulation status checks for high-voltage switchgear, ring main units, voltage/current transformers, transformers (including dry-type transformers), GIS, overhead lines, cables, and other equipment. The degree of electrical discharge in equipment is measured by the following indicators:

Partial Discharge Intensity Detection: The intensity of partial discharge is characterized by measuring the discharge signal within one power frequency cycle, based on the peak values (dB) in the discharge pulse sequence.

Partial discharge frequency detection: The device measures the discharge signal within one power frequency cycle, extracts discharge pulses, and characterizes the frequency of partial discharge based on the number of discharge pulses.
