Product Description

GDCT-9500B Wireless HV LV CT Turns Ratio Tester


General Information 

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.

 

Features 

• The current clamp is made of special alloy, adopts the latest CT technology and magnetic shielding technology, and is almost immune to the influence of external magnetic field, which ensures high precision, high stability and high reliability of constant monitoring.
• Clear LCD display of main unit, super large storage, it can store 3000 groups of data.
• Monitoring software has online real-time monitoring and historical query function, dynamic display, with the maximum, minimum, average value indication, alarm value setting and alarm indication function, with historical data reading, storage, query and printing.
• High voltage tester, connected with insulating rod of 5 sections, can be used to measure current in lines with insulating layer below 60kV, or in HV/LV circuit of bare wire below 35kV.
• By pressing or pulling insulating rod, the special HV current clamp and test lead are easy to be removed.
• The insulation rod is light, with characteristics of moisture-proof, high temperature resistance, shock resistance, bending resistance, high insulation and telescopic.
