Product Description

Portable high voltage PD detector GDJF-2008



GDJF-2008 Partial Discharge Detector 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, a 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.

Used Condition
 
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 an environment with no dust and corrosive, good ventilation. It should not be interfered by strong electromagnetic
