Abstract
Frequency Response Analysis (FRA) has been approved and there is an increased interest in performing electric power transformers tests. The drawback of using the FRA method is that there is no available recognized standard to interpret the obtained results, which depend on personal expertise. For further understanding of the FRA signature of power transformers faults, it was recommended to use lumped or distributed circuit approaches, therefore understanding the fault effect on the FRA signature. This study presents a power transformer model and simulates its FRA. Also, the effect of reducing the model electrical circuit RLC parameters was investigated. The effect of each parameter was determined in the FRA spectrum. The results show a significant change in a specific region for each parameter.
