The process of periodic planned inspection, replacement or repair of all switch-gear and ancillary equipment installation in buildings and substation installations is called substation maintenance. This process involves a series of stringent physical and visual inspections or actions according to a set schedule. All these are done to make sure that the substations are kept in good working conditions.
Replacement of equipment can involve a standard procedure or take place only upon detection of damage, wear or substandard operation. All inspections and actions during this process are supposed to be documented accurately and then stored for future reference. This helps to prevent any similar damage or wear in future.
Immediate repairs in an electrical supply grid are very important. This is because failure of a any part of the substation equipment can result to a total collapse which may require days to rectify. For this reason, substation maintenance and care department is one of the most important sections of management. Minor maintenance will hardly require power shut down but major events will require few intervals of supply interruption. Keep these in mind and for real, your electrical grid will never let you down.
