Analyzing a 440/55V 3-ph Transformer Characteristic Using SFRA Technique

Abstract

Power transformer is the most expensive equipment in power system, and because the function of power transformer pivotal for utilities, hence the reliability of power transformer is required during the prohibition aspects in the power system. Consequently, a new technique must be invented for detecting the three phase transformer operations that must be always investigated whether it is operating as it should be or not. In this paper, the characteristics of a 440/55V three-phase transformer will be detected using Sweep Frequency Response Analysis (SFRA), which is a powerful graphical technique used for detecting varied characteristics in three-phase transformers.
