Bushing power factor test
WebThe excitation current test is a routine measurement that can be used to detect major problems in the magnetic core structure and winding defects, like shorted turns. An excitation current measurement is often performed as a standalone test using a power factor test set, as it is normally made at rated frequency and voltages up to 10 kV. WebThe test results for the transformer’s power-factor overall winding tests were not acceptable for service, with power-factor values greater than 1.0 percent for low-voltage and high-voltage windings (Cl & CH). Bushing power-factor values, the C1 test as given in Table 1, were also higher than acceptable for in-service bushings of this type.
