How to use the wire clamp resistance tester resistance test
Reduce the power line tower grounding resistance can improve the lightning withstand level, reduce lightning accidents, reduce the contact voltage and step voltage in near the tower, and prevent the accident. Therefore tower grounding resistance is an important data. All aspects of design, construction and operation must attach great importance to accurately measure the true the numerical, which is lower than the set value. The past is the use of ground shaking table to measure the grounding resistance, but due to the need from the measuring line grounding outwards over 100 meters and two auxiliary electrode connected to the workload, and often affected by terrain and environmental constraints, the auxiliary electrode position can not meet the requirements therefore, it is difficult to measure the correct result. In recent years the introduction of clamp type earthing resistance tester, because of its simple measurement method, welcomed by the line for the majority of workers.
Clamp tester grounding resistance with long jaw and jaw round points. The long jaw, especially suitable for flat ground applications. In addition, the leakage current and neutral current ETCR2000 forcipated grounding resistance instrument can also measure the ground system.
The clip on earth resistance tester is mainly used for measuring grounding resistance of electric power, telecommunications, meteorology and other electrical equipment. Using this method of measurement, without auxiliary electrode, there is no pole error. Repeat the test, the consistency of the results is very good. The relevant departments of the state of a ground resistance tester and compared with the traditional voltage current test results show that it can completely replace the grounding resistance of the traditional test methods, accurate measurement of grounding resistance. In practical application, the 2000 series of the clip on earth resistance tester in all walks of life, different service environment, the majority of customers get the recognition.
