Product Description JF-2004 Portable Switchgear and Transformer Partial Discharge DetectorProduct DescriptionJF-2004 Portable Switchgear and Transformer Partial Discharge 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. 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.
