"Permanent availability is one of the key parameters of electrical energy. To ensure its permanent availability it is necessary to perform diagnostics and maintenance actions. Especially high voltage transformers and generators must be monitored. Diagnostic tests describe the state of operated machines and thus enable operators to make decision about maintenance. The main degradation mechanism that affects the life of power transformers is the temperature. Especially hot spot temperature has to be monitored and evaluated. This paper presents the procedure of online computation of hot spot temperature on the basis of online diagnostics. Hot spot temperature can be further used for online residual life calculation." .
