<p>PURPOSE:To greatly reduce the number of taping processes of an insulating tape by a method wherein an insulating later which is formed between a secondary winding and a tertiary winding for a current transformer is formed of a resin-molded cover instead of winding an insulating tape. CONSTITUTION:A secondary winding 4 is wound on a core case in which a high-permeability magnetic-material core has been housed; a secondary-winding wound core 5 is formed; an insulating layer on the secondary-winding wound core 5 is formed of a resin-molded cover A; a tertiary winding 7 is wound on the resin-molded cover A; a tertiary-winding wound core 8A is formed.</p> |
