Applications

MORORW-PD-S4D Four-channel digital partial discharge comprehensive analyzer adopts compact design and is connected by remote PC or laptop control via TCP/IP network. The instrument is suitable for type test, factory test and acceptance test of high-voltage products, and can complete quantitative test of partial discharge of motors, mutual inductors, cables, bushings, capacitors, transformers, lightning 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. PD measurement under DC voltage can be used as an option for standard instruments.
