Product Description
GDJF-2008 Partial Discharge Detector

Product Description
GDJF-2008 Partial Discharge Detector is measuring partial discharge for the products  such as 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 well equipped 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.
 
Features
Ambient temperature: 0-40ºC±2ºC
Relative humidity: ≤80%
Power supply: 220V±10%, 50HZ
No violent vibration and mechanical shock
The device should be placed in the environment with no dust and corrosive, good ventilation. It should not be interfered by strong electromagnetic.
Earthing requirements: earthing resistance <1Ω
