Mathematical model for building the resource characteristics of power transformer, operating in the overloading mode

Abstract

The paper presents the mathematical model which allows to determine the allowed operation term of the transformer in the overloading mode without the decrease of general operation period on the known environmental temperature, level of overloading and loading value, which took place prior to the overloading moment. There had been built the resource characteristics of the transformer of ТСГЛ type (three phase dry transformer with geofol insulation) with the demonstration of its application.
