CA6472 + CA6474 high voltage transmission tower integral earthing resistance test

High voltage transmission tower test suite, includingmultifunctional ground resistance tester CA6472 and GroundFlex ® tower test box CA6474. This test system is currently on the market only, can continue to open groundconditions, measuring pole each foot tower grounding resistance, and the tower of the grounding resistance.This and the traditional measurement methods, namely the need to disconnect the method to measure theoverhead ground wire compared, will save a lot of manpower and resources, while in the test security isgreatly improved.

Including the main features, this test system can measure the tower: tower foot (or all) and overhead ground wiregrounding resistance. The current signal injection testingfrequency of 5KHz, current of the frequency signal and measure the flow through each of the towers of the foot,can be used to understand the grounding resistancecharacteristics of the whole tower when lightning stroke occurs (the impulse grounding resistance).
