Abstract

One of the equipment’s that has a very important role in electric power transmissions systems is the power transformer. The failures of the power transformer frequently cause interference with the transmissions systems. Therefore the condition and performance of the power transformer should be known, it includes reliability and security. This paper proposes the analysis of risk resources and failure probability of power transformer using Failure Mode Effect and Criticality Analysis (FMECA). An example was taken from 92 power transformer to illustrate the FMECA method. Based on the investigation there are three components having the potential failure modes; winding, OLTC and bushing. In this case, winding has the highest failure probability. The severity and occurrence are divided into 10 levels, while detectability is divided into 5 levels. As a result, the degree of criticality for winding is high, for load-tap-changer (OLTC) and bushing are medium. The maintenance strategy for winding is maintenance immediately, for OLTC and bushing are maintenance priority.
