Abstract

PURPOSE: To obtain a small-sized economic current transformer whose static capacity can be made smaller by arranging the primary iron core and the supplementary iron core concentrically; and arranging the supplementary iron core outside the primary iron core.
CONSTITUTION: The primary iron core 21 and the supplementary iron core 22 are provided so as to effect the primary current each other, the primary iron core 21 and the supplementary iron core 22 are arranged concentrically, then the supplementary iron core 22 is arranged outside the primary iron core 21. The secondary induced voltage occurred in the secondary winding 29 wound on to the primary iron core 21 is amplified by the second secondary winding 26 wound on to the supplementary iron core 22, so that the exciting current becomes zero. After making smaller the static capacity between the primray winding 23 and the secondary winding 26 of the transformer, the influence of noise on the signal processing portion is reduced after current detection.
