Grounding system inspection Or ground system Is the first visual inspection To see the connection of the ground system And the grounding system Check the connection strength. Deposit of ground wires in electrical systems. Measuring grounding resistance Synchronization test Of the ground rod by measuring the continuity of the earth ground connected in the electrical system Because incomplete ground systems can affect the quality of the electrical system.
Over time Abrasive ground Highly refreshed High salinity And high temperatures can cause the ground to fall And connected to deterioration Therefore, even if the ground ground has a low ground resistance value when first installing, the resistance of the ground system may increase if the ground ground is worn down.
Ground testing equipment Is a tool for evaluating the problems of electrical ground systems Uncertain The problem may be related to improper grounding. Or the power quality is poor
This is why there are suggestions to check the ground and ground connection at least every year. As part of your regular preventative maintenance plans In this routine examination If the resistance is increased by more than 20%, technicians should examine the root cause of the problem. And take corrective actions to reduce resistance by changing Or supplementing the ground principles in the ground system
