Product Description

Portable Digital Partial Discharge Free Detector GDJF-2008




GDJF-2008 Partial Discharge Detector is measuring partial discharge for the products  suchas transformers, 
mutual inductors, HV switches, zinc monoxide arresters and power cables. It also can make type tests and monitor insulation operation.This type has the advantages of high sensitivity, wide range of capacitance, being 
wellequipped for input unit impedance detecting and more variants of frequency bands ( 9 in all). After proper setting, the discharge impulse amount can be read directly. The indicating and digital meters are shown simultaneously.
This detector is widely applied in power stations, manufacturers and institutions.
