<P>PROBLEM TO BE SOLVED: To provide a gas-insulation instrument transformer that has no possibility to cause damage to a monitoring apparatus by suppressing electromagnetic or electrostatic induction between a lead wire of a secondary coil and a primary coil. <P>SOLUTION: In a gas-insulation instrument transformer in which a secondary coil 2 and a primary coil 4 are wound around the outer periphery of a core 1, the secondary coil 2 includes a winding part in which the layer number is odd, a primary lead wire 21a that is formed at one end of a conductive wire constituting the winding part and that is drawn out of one end face of the winding part, and a secondary lead wire 21b that is formed at the other end of the conductive wire and that is drawn out of the same end face 23a as the primary lead wire 21a through a gap formed between the core 1 and the secondary coil 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
