Maintenance-free earthing is a method of earthing that is designed to require minimal maintenance and to last for an extended period of time. This type of earthing system is typically used in electrical systems where it is not practical or feasible to perform regular maintenance on the earthing system. The main idea behind maintenance-free earthing is to use materials that are resistant to corrosion, deterioration, and degradation, thus reducing the need for frequent inspections and maintenance.
