Abstract

PURPOSE: To secure and facilitate a measurement even at a high and narrow place, by fitting an electric-wire inserting guide projection to the opening-shutting part of clamp type CT.
CONSTITUTION: Although electric-wire inserting guide projection 3 is formed at the opening part for electric wire insertion at the tip of moving iron core 2 in one body, it should be fixed by post-work. Consequently, when moving iron cores 2 are spread against springs 7 and measured electric wire 11 is inserted to measure electric flowing through measured electric wire 11, only bringing measured electric wire 11 into soft contact with electric-wire inserting guide projection 3 inserts it automatically and also closes the magnetic circuit of ring-shaped iron cores made up of moving iron cores 2 and fixed iron cores 1. Further, the electric wire can be inserted and extracted by displacing each of moving iron cores 2, 2 mutually a half as much as the diameter of measured electric wire 11 to be inserted, and consequently the displacement for spreading is reduced, so that the measurement will be facilitated at a narrow place.
