PURPOSE: A zero-phase-sequence current transformer which includes a case cover is provided to easily perform a dipping process of a pin by forming a protrusion on the outer circumference of a case. CONSTITUTION: Two holes(114) passing through a protrusion(112) are formed. A pin(120) is respectively mounted to the two holes. A coil line is dipped to the upper side of the mounted pin. One end of the pin is fixed by being pressed the upper side. An expansion unit is formed at the upper side of the holes. A case(110) is covered by a case cover. The protrusion is projected from the one side of the case. A concave unit in which the coil line of a core is wound is formed on the pin. A stopper for controlling the length of the pin passing through the case is formed in around the concave unit. |
