JF-2004 Easy Use Portable Transformer Partial Discharge Detector
Introduction:
The detector is used for the detection and evaluation of the insulation status of high-voltage switchgear, ring network cabinets, transformers, GIS, overhead lines, cable terminals, cable branch boxes, and other equipment.
It is widely used in the following fields:
Partial discharge intensity detection: By measuring the discharge signal within a power frequency period, the intensity of partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence.
Partial discharge frequency detection: The device measures the discharge signal within a power frequency period, extracts discharge pulses, and characterizes the frequency of partial discharges according to the number of discharge pulses.
