Abstract
A computer program for the calculation of the transient performance of a current transformer during short-circuit conditions is discussed. A numerical analysis that includes the dynamic hysteresis loops is used to calculate the performance, and results are compared with those of direct laboratory tests. The test methods, proposed in IEC Document 38 (Central Office) 78, are discussed. Results show the calculation can successfully replace expensive laboratory tests.
