Abstract
A voltage detector having 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. Also provided is a conductive casing in which the voltage detection printed board is fixed, wherein, when a conductor, in which 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.
Claims5
