Product Introduction

The MOEORW-WPD-S4D multi-channel partial discharge (PD) test set features a compact design and can be remotely controlled via a PC or laptop through a TCP/IP network. This instrument is suitable for type testing, factory testing, and acceptance testing of high-voltage products, and can perform quantitative testing of partial discharge in motors, transformers, cables, bushings, capacitors, transformers, surge arresters, switches, and other high-voltage electrical appliances. The digital partial discharge detector meets IEC60270 and GB/T7354-2018 standards and can measure and record partial discharge (PD) and AC test voltage. DC voltage PD measurement is an optional feature of the standard instrument.
