PURPOSE: A one point sensing type power measuring device is provided to obtain current information passing through an electric wire. CONSTITUTION: A one point sensing type power measuring device is composed of an opening core(1), a coil(2), and a signal interpretation circuit unit(3). The g core collects a magnetic line of force generated by current wave form passing through an electric wire. The coil is wound on the center of the opening core and minimizes a deflection portion of the opening core. The signal interpretation circuit unit is connected with the coil and interprets an induced electromotive force signal collected from the coil. The signal interpretation circuit unit inversely operates current information.
