【Abstract】 To resolve the error and disturbance with a simple way for the test of CVT without disconnecting the wires, this paper introduces how to perform the test on CVT without disconnecting the wire with the frequency-conversion bridge, and what we should pay attention to in the test. When C2 is measured, the voltage of the inter transformer should be less than 2.5 kV, and the test frequency is between 40 to 47.5 Hz. Test data make it clear that this method adapts to on-site test.更多还原
