Electrical Equipment’s Condition and Remaining Useful Life Assessment – a Review

Condition-based maintenance (CBM) is a preferable type of maintenance nowadays in power utilities. Assessment of equipment’s health condition and remaining useful life (RUL) is the main goal of CBM in order to allocate resources correctly and optimally, to make system more reliable and to reduce overall costs for the maintenance. There are a lot of methods and techniques used for condition and RUL assessment. This paper presents general approach for CBM and through the review of references presents three common techniques – ranking and scoring health index method, artificial neural network method and fuzzy logic method for evaluating electrical equipment’s condition. In the end, comparison of mentioned methods is briefly presented.
