Assessing the Reliability of Power Transformer by Quantitative Fault Tree Analysis

Abstract:

The purpose of this paper is assessing the reliability of power transformer for a switchyard by quantitative fault tree analysis. First step is determines if the fault tree is static or dynamic. To generated exact calculated results, the static entities are computed using standard combinatorial techniques. The dynamic entities are transformed into equivalent Markov models. The results for these various entities are then brought together using techniques employed for generalized fault tree analysis to produce exact calculations. The reliability of power transformer systems of GI Simangkuk switchyard in Indonesia was assessed and the main contributors have been identified. This result will help the decision maker to improve the reliability of power transformer system.
