Abstract
A current detector includes a ring-shaped core for inserting a wire; a detection winding on the core; and resistor connectors for connecting a resistor in series to the detection winding. The detection winding has a first winding at a first end and a second winding at a second end that are connected in series. The first winding and second winding each have n (where n is three or higher) first or second unit windings in series. The core surface is partitioned into 2n regions around the core. The first unit windings are formed in odd-numbered regions and the second unit windings are formed in even-numbered regions. A j(where j is 1 to n) first unit winding from the first end and a jsecond unit winding from the second end are not adjacent and are formed with an equal number of turns.
