An asset management tool using a simple technique for determination of maintenance priority level of medium voltage transformers is presented in this paper. Case studies during implementation of the decision tool on transformers with a decreased in oil quality are also discussed in this paper. Among the investigated cases, a transformer with a declined breakdown voltage and an excessive production...
Power transformers are important and expensive components in electric energy networks. Unplanned outages of power transformers has a higher economical impact, which motivates, preventive tests and diagnosis for tapping the benefit of predicting condition to optimize maintenance and increase reliability of power system. Application of advanced diagnostic techniques for power transformers, provide the...
This paper deals with the practical importance of condition monitoring for power transformer in the electrical engineering field. A review has been made of the modern development in this technology. Some empirical relations have been established by using several practical data of different transformers. Practical test data of one of the State Electricity Boards of India has been taken & analysis...
