GDCT-9500B Wireless HV CT Turns Ratio Tester is designed for online measurement of high voltage CT, primary current , secondary current, turns ratio, polarity, leakage current of transformer 60kV and below (such as: 10kV or 35kV).
It can also be used as high-precision low-voltage clamp ammeter and leakage ammeter If the insulating rod is not used. It is integrated with functions of meter below: high/low voltage clip-on ammeter, high-altitude current telemeter, high-altitude leakage current tester, high precision clamp leakage ammeter.
It is composed of special high voltage tester, LV current clamp, main unit, HV insulating rod, monitoring software, communication line and so on, Wireless data transmission can penetrate wall barriers, linear transmission distance of 30 meters.
It is widely used in the substation, power plants, the auditing departments of electric power, industrial and mining enterprises as well as the testing station, electrical maintenance department and so on.
