Transformer condition monitoring

Due to increase in age of the power transformer park it is necessary to solve the problem a residual resource. Recently, with this purpose periodic inspection techniques of energized and off-line transformers are used to estimate technical transformer condition and to give recommendations on prolongation of service life. In this paper Transformer Diagnostics Monitoring (TDM) system is described as system most fully assess condition all transformer parts (windings, core, bushings, LTS, oil, etc).
