The paper provides a short insight into the structure of Latvian high voltage transmission network, describing existing system of complex diagnostic and analyzing maintenance data to reveal the most frequent locations of faults in power transformers. Modified inspection schedule of power transformers is described that serves as a base for developing effective algorithm for assessment of technical condition by using transformers’ maintenance data, considering the results of diagnostic tests and including prediction of remaining service life. Calculations, performed by Weibull cumulative distribution function, for determining service life of the tap changer of 2 power transformers are presented as a case study.
