Also they do not trip or blow when oven-stressed (except under extreme conditions), transformers are frequently overloaded and allowed to operate well beyond its capacity. However, use and ageing of electrical installations, similar to other installations, is an origin of normal deterioration in electrical equipment that can be accelerated by factors such as a hostile environment, overload, or severe duty cycle. Other causes of deterioration may be load changes/additions, circuit changes, improperly set/selected protective devices and changing voltage conditions. However, equipment failure is not inevitable if a checking and preventive maintenance programis established. 1.
