Patent ID: 8629674

Claim:
A current and voltage detection printed board, comprising: a board formed with a penetration hole; a first pattern wire formed at a periphery of the penetration hole; a second pattern wire formed at the periphery of the penetration hole; a plurality of first through holes that penetrate the board between the first and second pattern wires; a third pattern wire formed at the periphery of the penetration hole; a fourth pattern wire formed at the periphery of the penetration hole; and a plurality of second through holes that penetrate the board between the third and fourth pattern wires, wherein, when a conductor in which an AC voltage is generated and an AC current flows is disposed so as to pass through the penetration hole, the first and second pattern wires and the first through holes are formed so as to function as an electrode of a capacitor to detect the AC voltage generated in the conductor, and the third and fourth pattern wires and the second through holes are formed in a coiled shape so as to function as a current transformer to detect the AC current flowing in the conductor.
