発明の名称 (英語) ELECTRICAL POWER MEASUREMENT DEVICE コモンズ
発明の概要(英語) An electrical power meter that utilizes a magnetic thin film is required to be mountable to wiring that has already been disposed and to be able to define the positional relationship between the wiring and the magnetic thin film regardless of the position at which the power meter is attached to the wiring. Provided is an electrical power measurement device characterized by comprising the following: a sensor part that is connected to a circuit to be measured via a pair of connection terminals, and that is provided with the pair of connection terminals for connecting to a power source in parallel with a load, a magnetic element provided with element terminals on either end of a magnetic film, a measurement resistor connected in series to the magnetic element, and a detection means that detects voltage changes in the magnetic element and outputs a prescribed component; a sensor unit comprising a plurality of the sensor parts; an addition means that adds the outputs of the detection means of all of the sensor parts; and a securing means that secures the magnetic elements of the sensor parts in positions at equal distances from a virtual axis, which serves as a positional reference for disposing one electric wiring, in orientations facing the virtual axis.
