Test for Error of Current Transformer Based on Low-voltage Extrapolation Method

摘要：

The extrapolation method for the error test of the current transformer is to tests the current transformer on-site as a voltage transformer with the same error, which firstly test the error, admittance and other parameters of the trans-former at 200％to 1000％ rated voltage or current, then test the admittance at l％to 120％ rated voltage or current, and finally achieves the error through the calculation. Its application will bring a great influence on the test of the current transformer on-site.
