<p>PURPOSE:To achieve miniaturization and reduce weight by thinning a primary winding conductor while securing a specific rated current resistance of a winding type current transformer. CONSTITUTION:In a winding type current transformer 1 where a primary winding and a secondary winding are laid out concentrically for a core 31, the primary winding is constituted of a plurality of split primary windings 11A and 11b which are laid out in the periphery direction of the core 31 with a spacing and are conductively connected in series, and the total of the number of turns N1a and N1b of the split primary windings 11A and 11B matches the number of turns of the primary side determined by a current transformation ratio and the number of the secondary windings.</p> |
