Description

One of the most important devices in the power system is the power transformer, which supply with suitable voltage all consumers. A thorough analysis of the operation failures of power transformers in the power system, would help to understand the impact of faults on their processes and daily operations. Given that the performance of this device is quite important then it is vital to prevent faults which may occur in it. Transformer failures in power systems not only reduce the reliability of the power system, but also have significant effects on the quality of electricity which is delivered to consumers connected to the network. This paper generally deals with the transformer, its characteristics and phenomena that may occur during its operation, while in a more specific way it deals with the ways of testing of transformers. Inspection . and diagnostic testing will always be a key factor in determining the operating condition of the transformer and help to select the appropriate corrective measures to ensure reliable operation which would then result in extending the life of the transformer. For this reason, the paper is focused on the importance of transformer testing, as a result of which the numerous faults that can occur in this device can then be prevented.This paper will discuss the techniques and types of testing applied in the testıng of transformers ın the Kosovo Dıstrıbutıon System, case study – Transformer TR2 in Substation 35/10 [kV] “Xerxa”. The working methodology for the preparation of this paper is based on the practical knowledge and scientific research about worldwide experiences for the testing of oil power transformers.
