Power Frequency Ground Resistance Test Equipment , Large Current Injection , Substation Grounding Resistance Test Set

I. Product Introduction :

Power plant and substation grounding grid is one of the important facilities to ensure personal safety and safe operation of electrical equipment; the size of grounding resistance of grounding grid is an important indicator to measure grounding. Hence, our device is designed and manufactured to meet the requirements of Department of Energy's "grounding-frequency characteristic parameter measurement guidelines".

DZC series Power Frequency Ground Resistance Test Equipment is power frequency and large current injection test set for grounding resistance measurement.The device consists of console and transformer, and handling, wiring, and use are all extremely easy.
