Abstract
Sensitive elements of current sensors for three-phase circuits based on delay lines on surface acoustic waves, where the impedance connected to a reflective counter-pin converter depends on the current in the conducting bus, have been studied. The impedance is a series-connected inductor with a ferrite core and a capacitor. The inductance changes under the influence of the magnetic field created by the current, and the capacitance depends on the voltage induced in the winding wound on a magnetic wire located around a current-conducting wire or bus. It has been shown that it is better to use closed magnetic circuits without a permanent magnet, but with a winding wound on it, the voltage from which is fed through diodes to varicaps or to an additional winding located on a ferrimagnetic core of a magnetically sensitive inductance. In this case, the positive and negative half-waves of the alternating current are measured independently, which allows us to estimate nonlinear distortions in the power grid and more accurately evaluate the power consumption. The use of a varicap circuit as a capacitor can significantly increase the sensitivity and accuracy of current measurement. The use of sparse counter-pin converters allows significantly reducing the operating frequency band, which makes it possible to measure currents simultaneously in three phases in the range of permitted frequencies of 2400–2483 MHz. In general, the use of sensors of the new design will expand the dynamic range of measured currents.
