The Research Of Transmission Line Tower Grounding Resistance Measurement Method

The measure of grounding resistance was a necessary means to check whether grounding devices could reach a point of order request.Accurately measured grounding resistance could verify the designment of grounding system whether or not reasonable.Timely found grounding system changes or defect, avoided of the failure ground to make economic loss or accident.This article researched several meathods of transmission line tower grounding resistance through measured and calculated.Carefully studied the error characteristics of two typical clamp grounding resistance tester under the situation of the different resistors and inductors.With the actual site improvements to enhance clamp grounding resistance tester for accuracy, to content the needs of power system tower grounding resistance. Combined the specific circumstances of ShenYang,summed up measurement methods of tower grounding resistance suitable for this region. It's easy for the people of power system to master and use grounding resistance measurement methods and measure grounding resistance with accuracy.
