WDJF-9209 Handheld Multifunctional Partial Discharge Inspector

WDJF-9209 multi-functional partial discharge inspection instrument is a multi-functional hand-held instrument. It is based on the ground wave, ultrasonic, ultra-high frequency and high-frequency current detection methods to test the partial discharge of the equipment, and can read the partial discharge amplitude and spectrum waveform. It can provide storage and readout functions of two-dimensional and three-dimensional maps, which can better evaluate the partial discharge of electrical equipment. The multifunctional partial discharge inspection instrument is suitable for partial discharge detection of electrical equipment such as GIS, switch cabinets, transformers and power cables. The equipment is portable and easy to operate, and all detections do not have any impact on the operation of high-voltage equipment. The product can observe the measurement signal in multiple cycles, identify the discharge frequency, and analyze it through various modes, which can clearly determine the fault
