4. Fast test for excitation check • 10kV knee point check time: 50s • 1kV knee point checktime: 15s Excitation characteristics test based on DC method <Conventional method> □ Can check CT with high knee point value □ High efficiency, high accuracy, more safe Error check with extrapolation method for AA type CT □ Get the ratio error and angle error based on extrapolation method, no need to use extra standard CT nor standard load. Ratio test based on voltage method <Conventional method> Current source is at primary side .. urrent meaf uremenMi jM ^tg^^o^fffiijf■lifefe ^ Voltage source is at...
