Two-Stage Current Transformers Based on Nanocrystalline Materials for Electronic Energy Meters
Abstract:This paper deals with developments of iron-based nanocrystalline materials for current transformers well adapted for electronic watt-hour meters. A design of a 100A two-stage current transformer with 100 Hz–10 MHz frequency bandwidth is presented. Stress- or field-annealed Fe74.5Cu1Nb3Si15.5B6 nanocrystalline ribbons are used. They exhibit high saturation level, linear B-H curve, low remanence, low core losses at medium frequency, exceptional thermal stability of magnetic properties. Furthermore, in these low coercive materials, it is possible to easily induce a few thousands J/m3 anisotropy energies.
