Substation maintenance is the process of inspecting and, if required, repairing and replacing all switchgear, buildings, and auxiliary equipment in substation installations on a regular basis. Substation maintenance, in its most basic form, is a routine of preventive inspections and activities performed to keep substations in excellent operating order. This procedure generally comprises a series of severe visual and physical inspections and activities carried out in accordance with a predetermined timetable. Equipment replacement is a normal procedure performed only when wear, damage, or poor functioning is detected.
