What steps are required for maintenance of earthing in electrical installations?

Proper maintenance of earthing in electrical installations is essential to ensure the safety of individuals, equipment, and buildings. A well-maintained earthing system protects against electrical faults, reduces the risk of electrocution, and ensures the proper functioning of electrical devices. The following steps are required for maintaining earthing in electrical installations:

1. Regular Inspection – Periodic inspection of the earthing system should be carried out to check for corrosion, physical damage, or loose connections. A visual inspection of grounding electrodes, conductors, and connections helps identify potential issues.

2. Measurement of Earth Resistance – The resistance of the earthing system should be checked regularly using an earth resistance tester. The measured resistance should be within the permissible limits specified by electrical standards. If the resistance is too high, ______ ____ _________ _________ ____.
