Current transforming circuits

摘要

Current transforming apparatus comprising a current transformer and means for developing a current substantially expressed by axI2, wherein I2 denotes the secondary current of the current transformer. Impedance means is connected in series to a load of the current transformer and has an impedance (Z2+ZL)/(a-1), wherein Z2 is the secondary leakage impedance of the current transformer and ZL is an impedance of the load. A current-voltage converter may be employed as the load of the current transformer.
