1.1 Brief Introduction

The digital partial discharge detector features a compact all-in-one design for easy operation. It is suitable for type testing, factory acceptance testing, and handover testing of high-voltage products, enabling quantitative measurement of partial discharges in motors, current transformers, cables, insulating bushings, capacitors, transformers, surge arresters, switches, and other high-voltage electrical equipment. Compliant with IEC 60270 and GB/T 7354-2018 standards, this instrument can measure and record partial discharges (PD) as well as AC test voltages.

2 Testing System
2.1 System Survey

The partial discharge testing system is a data acquisition and analysis tool designed to detect, record, and analyze partial discharge events, with applications spanning various fields. It is suitable for type tests, factory acceptance tests, and handover tests of high-voltage products, enabling quantitative measurement of partial discharges in motors, transformers, cables, bushings, capacitors, surge arresters, switches, and other high-voltage electrical equipment—ideal for both laboratory use and field measurements.
