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 facto…See more on electricaltechnology.orgPublished: Mar 16, 2018The art of transformer maintenance, inspection and repair ... 02, 2020The primary purpose of transformer maintenance is to ensure the internal and external parts of the transformer and accessories are kept in good condition and "fit for purpose" and able to operate safely at all times. A secondary and equally essential purpose is to maintain a historical record of the condition of the transformer.
