Abstract (en)

[origin: WO2007101916A1] The invention relates to a method and apparatus for measuring electrical power travelling in a conductor (3). In the apparatus there are means for measuring simultaneously voltage (U) and current (I). The apparatus according to the invention comprises means (2, 22, 27) for converting the voltage (U) in a current quantity in a mechanical element (1, 21), which is in a force-effect relationship relative to the conductor (3), and means for determining the force-effect between the mechanical element (1, 21) and the conductor (3, 23), so that the force effect is directly proportional to the product of the voltage (U) and the current (I).
