Ground Continuity Tester

The electrical integrity of earthing device is the electrical connectivity among all kinds of electrical devices that should be grounded or the electrical connectivity between ground equipment all parts and devices, it is DC resistance value; it is also known as electrical conductivity. Ground down lead and earth mat of electrical equipment reliable and effective connection is the fundamental guarantee of instrument safety operation. Ground down lead is the connection part of electrical equipment and earth mat. In the long-term running, the connection part may be rusty even ruptured due to moisture and other factors, which will cause the resistance increases which at connection point of ground down lead and the main earth mat, and thus cannot meet the requirements of electrical power regulations and standard. It also cause the instrument hides danger in work, seriously even cause the instrument run in lost ground status. Underground ground electrode and its connection parts may rusty, and even ruptured. Therefore, it is necessary to regularly do the electrical integrity test of grounding devices.
