ABSTRACT:
A magnetic core for a current transformer, and a current transformer and a watt hour meter used thereof, which is preferred the detection of a alternate current with a large asymmetrical waveform and a alternate current which a direct current is superimposed are realized. A magnetic core for a current transformer comprising the composition represented by the general formula: Fe100-x-a-y-cMxCuaM′yX′c(atomic %), wherein M is at least one element selected from Co and Ni, M′ is at least one element selected from V, Ti, Zr, Nb, Mo, Hf, Ta, X′ is at least one element selected from Si and B, and x, a, y, and c meets the composition of 3≦x≦50, 0.1≦a≦3, 1≦y≦10, 2≦c≦30, and also 7≦y+c≦30, and an alloy comprising a crystal grain consisting of at least a part or all of the composition with a mean particle size of less than or equal to 50 nm.
