An endless supply of electricity is taken for granted in today's world of commerce and business. Our dependence on a continuous supply of power, drives the search and development of reliable methods for the preventive diagnosis and maintenance of transformers. This paper primarily refers to measurements of insulating resistance in distribution transformers, at several temperatures, and thereafter to calculations of the thermal coefficient of the transformers. It overhauls the above characteristic magnitudes of 24 distribution transformers and indicates the observations and comments on ageing and remnant life of the insulation system of the transformers. A method for transformer life cycle prediction is suggested. (c) 2007 Elsevier Ltd. All rights reserved. (EN)
