WebThe low voltage bushing C1 and C2 test results are given in Tables 3 and 4 respectively. There were no nameplate test values or prior field test data available for comparison purposes, however the C1 power factor values appeared elevated, ranging from 0.52% to 0.81%. The C2 measured power factor values WebThe following tests were performed at the substation after the unit was oil filled: • Transformer turns ratio on all taps • Insulation power factor of transformer and all bushings (C1 and C2) • 10-kV excitation on all taps • Core ground and winding resistance • Oil quality and dissolved gas analysis (DGA). buckboard\u0027s a
Bushing Condition Assessment and Troubleshooting
WebBushing Tests. For bushings that have a potential tap, both the capacitance between the top of the bushing and the bottom tap (normally called C1) and the capacitance between the tap and ground (normally called C2) are measured. To determine bushing losses, power factor tests are also performed. C2 capacitance is much greater than C1.
