Partial discharge detector

PD1 is a hand-held, pre-screening, tool-based professional live detection instrument. It can be equipped with 8 external sensors including AA/AE Ultrasound, TEV ground wave, HFCT high frequency current and temperature sensor. It is suitable for live detection of various electrical equipment such as substation, switch station and outdoor. This instrument adopts acoustic and electric joint detection method, using transient ground wave (TEV), ultrasonic wave (AE), high-frequency current sensor (HFCT) and other sensors to comprehensively detect the partial discharge of power equipment, to achieve direct monitoring of power equipment such as transformers, switchgear and distribution cables. The PD1 detector can evaluate the insulation condition comprehensively according to a variety of characteristics, detect the magnitude of partial discharge, and calculate the time difference between acoustic and electrical signals to achieve accurate discharge power location. PD1 has waveform detection, recording and storage functions, and has small size, light weight, is very easy to operate. It supports wireless data uploading, cloud platform interconnection, GPS positioning, effectively preventing line faults and improving power cable reliability.
