<p>PURPOSE:To enhance electric insulating performance of a titled apparatus and to omit a space for insulation use. CONSTITUTION:A shielding case 12 and a zero-phase current transformer are housed in a quadrangular synthetic-resin case 16 provided with a cylindrical part 16a which has been inserted into a through hole at the zero-phase current transformer; an electrically insulating filler 17 is filled. Lead wires 2 of the zero-phase current transformer are led out from a corner part of the synthetic- resin case 16.</p> |
