CURRENT DETECTION PRINTED BOARD, VOLTAGE DETECTION PRINTED BOARD, AND CURRENT/VOLTAGE DETECTOR USING SAME, AND CURRENT DETECTOR AND VOLTAGE DETECTOR

摘要

A current detection printed board includes: a board having a penetration hole that penetrates the board; and at least one wire that is formed in a coiled shape having both ends by penetrating the board along the periphery of the penetration hole and alternately connecting a front surface layer and a rear surface layer of the board, wherein, when a conductor, in which an AC current flows, is disposed to pass through the inside of the penetration hole, a current flowing in the wire is output through electromagnetic induction.
