A New Approach for Estimating Insulation Condition of Field Transformers Using FRA
Advances in Electrical and Computer Engineering, 2020 Frequency response analysis (FRA) is a tool for evaluating mechanical integrity of transformer's core and winding. However, several studies have reported that FRA is also sensitive to other parameters such as temperature, moisture content and presence ...
