MSJF-6205 Two-Channel Digital Partial Discharge Detector
Couldn't load pickup availability
The digital partial discharge detector features an integrated design for easy operation. This instrument is suitable for type testing, factory testing, and acceptance testing of high-voltage products. It can quantitatively test 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.
