PASSIV WIRELESS CURENT SENSOR FOR THREE-PHASE CIRCUTS
Abstract
Studies on passive wireless current sensors for three-phase circuits based on delay lines on surface acoustic waves are presented. The design of a passive wireless sensor on surface acoustic waves is proposed, in which there is a strong dependence of the reflection coefficient of surface acoustic waves on the reflective counter-pin Converter, which provides high sensitivity and a large dynamic range of current measurements. In this case, inductive wound on a ferromagnetic core can be used as sensing elements, which are placed in the gap of the magnetic circuit located around the conductive wire or bus.
