As we all know, in the process of power system operation, in order to ensure the safety of the circuit, it is necessary to carry out grounding Settings. This ensures that after the circuit receives an internal overvoltage or lightning overvoltage, the current can find a safe distribution path through the ground to the ground. So how to ensure the safety of electrical system grounding? Of course, this depends on the ground resistance tester.
Bad grounding will directly block the circuit connection. In addition, if the circuit is poorly grounded, it can be dangerous and can cause other systems to fail. Grounding resistance testers do not need to disconnect grounding leads and auxiliary electrodes when measuring a grounded system with a loop. It is safe, fast and easy to use. This is an important tool for troubleshooting the circuit, which helps to maintain the normal operation of the circuit and the safety of the maintenance personnel.
Therefore, power workers need to test all grounding of the power system every year to ensure the safety of the entire circuit as part of the routine maintenance of the circuit. Through this regular inspection, if the resistance of the circuit is found to increase by more than 20%, the staff should check the cause in time, troubleshoot the fault, and replace the grounding rod or check the grounding system of the whole circuit to check whether there is a fault. Check for problems, reduce resistance and maintain circuit safety.
When using the grounding resistance tester, always wear insulation gloves, goggles, and other power protection devices. If the electrode is grounded prior to grounding it must be tested prior to grounding the electrode. Direct and accurate measurements can now be made with the new instrument while the electrodes are still connected.
