The electrical integrity of grounding device refers to the grounding device should be between all kinds of electrical equipment grounding device parts and the electrical connectivity between each equipment that is direct current resistance value also known as electrical conductivity. Reliable and effective connection between grounding lead and ground network is the fundamental guarantee of safe operation of power equipment. Ground down lead is electric power equipment and the connection part of the network in the long running process of electric power equipment joint is likely to be affected due to factors such as moisture rust a node or even the phenomenon such as fracture lead to ground down lead and the main grounding network connection resistance increases which cannot meet the requirements of power regulation problems in the operation of the equipment in safe hidden trouble caused serious ground operation. Corrosion and even fracture may occur to the underground grounding pole and its connecting part of the grounding device. Therefore it is necessary to test the electrical integrity of ground equipment regularly.
Electric power industry standard DL/T*******6 "guidelines for the grounding device parameters measurement regulation electric conductivity connectivity should choose special measuring instrument for 1 m Ω instrumentresolution accuracy is not lower than 1.0 on the Richter scale are unlikely. Our company is based on this The standard developed Ground Continuity Tester is a portable Tester with a high degree of automation which is specially used to test the electrical integrity of grounding devices. Its various technical indicators meet or are superior to relevant standards. Ground Continuity Tester is a simple and convenient operation high precision fast test speed good retesting performance and intuitive reading. It is an ideal special instrument in line with the requirements of regulations which greatly facilitates the development of test projects and improves work efficiency.
