WebPrinciples of Transformer Power Factor Test. The PF/DF tests measure insulation capacitance, AC dielectric losses, and the ratio of the measured quantities. When insulation is energized with an AC voltage, the insulation draws a charging current. This charging current comprises two components called capacitive current and resistive current. WebThe circuit constant values of the interwinding capacitance of transformer winding insulation are jointly governed by the design criteria, geometry, structural factors, and the materials used, respectively.3-6 Henceforth, it is easy to assume that the interwinding capacitance carries not only information regarding the winding-core arrangement but
