Frequency Response Analysis (FRA) is one of the best approaches to detect the mechanical integrity of transformer windings. FRA can be measured on-site or simulated based on the transformer’s design information. The calculations of Resistance (R), Inductance (L), Capacitance (C) and Conductance (...
