Prediction of Distribution Transformer Premature Failures
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
This paper deals with two types of Distribution Transformer failure analysis tests which can help in monitoring the Distribution Transformers condition. The three methods are Conventional oil test, Furan derivatives test. Conventional oil testing procedures determine the gas concentrations in the Distribution Transformers oil sample and analysing the defect by considering the ratio of two suitable gasses. Furan derivative analysis includes determination of Furan derivatives present in the Distribution Transformers oil sample and helps in deciding the Distribution Transformers insulation condition. A computer program was developed for which that can help in finding out the fault probability of the Distribution Transformer. Here, we demonstrate the application of these three methods on a 132/33kV, 15MVA Distribution Transformer from CSEB substation, Korba Bilaspur, India, under three different conditions namely healthy, moderately deteriorated and extensively deteriorated conditions and results obtained.
