Abstract
This paper describes a nonintrusive power measurement method that is suitable for a new type of low-cost and easy-to-install smart meters in measuring current and power from parallel electric cables based on noncontact magnetic flux and identifying the power consumption of each phase. By placing noncontact magnetic flux sensors close to the parallel electric cables that carry electric currents, a method for providing flux-to-current conversion and reducing mutual coupling effects among these cables is introduced. By using the mains voltage of the electronic control circuit as a reference, a new and simple method for accurately differentiating the phase currents and power in the cables is proposed. The proposed method has been verified with practical power measurements with reasonable accuracy for this specific application.
