Partial Discharge Detector
Model: HJF-500
The Partial Discharge Detector HJF-500 is non-invasive tool for measuring partial discharge activity of Switchgear, Transformer, GIS and HV cable etc. in running state. It is equipped with one built-in TEV(Transient Earth Voltage) sensor and one built-in Ultrasonic sensor, one external Ultrasonic sensor, one external UHF(Ultra High Frequency) sensor and one external HFCT(High Frequency Current Transformer) to collect partial discharge signals on medium voltage or high voltage equipment.
Main Features
●Non-invasive tool for online PD measurement in MV and HV substations
●Able to equip with 5 sensors, including 1 built-in TEV sensor(standard configuration), 1 built-in ultrasonic sensors(standard configuration), 1 external ultrasonic sensor(option configuration), 1 external UHF sensor(option configuration), 1 HFCT sensor(option configuration).
●Combines multiple functions in a single package
●Ultrasonic and TEV sensors for surface and internal PD
●UHF measurement can accurately measure PD activity in high bandwidth
●PD activity in HV cables is measured by using HFCT
●High sampling rate, strong anti-interference ability
●Provide time domain signal waveform, PRPD spectrum, PRPS spectrum etc. discharge patterns to realize the analysis of different discharge types.
●The test results can be stored on board, also can be uploaded to PC for generated test report.
