Patent Images
1. A voltage detector comprising:
- a voltage detection printed board including;
a board having a penetration hole that penetrates the board;
a first pattern wire formed at a periphery of the penetration hole;
a second pattern wire formed at the periphery of the penetration hole; and
a plurality of through holes that penetrate the board between the first and second pattern wires; and
a conductive casing in which the voltage detection printed board is fixed,wherein, when a conductor, in which an AC voltage is generated, is disposed to pass through the penetration hole, the pattern wires act with the conductor to function as electrodes of a capacitor.
