A Technique For Calculation Of Life Limits Of Electrical Network Equipment
The main attention in the article is paid to the method of calculating the limiting values of the life of the main electrical equipment based on a comprehensive assessment of the actual condition of the equipment, that is, its condition index. The basic principles of the developed technique are given and a structural diagram of calculating the maximum service life of electrical equipment is shown. A general model is proposed for calculating the resource limits of electrical equipment based on a linear approximation of the state index change function. The applicability of this method is illustrated by an example of calculation for a transformer unit.
