Abstract

The electromagnetic induction method generally is used to measure the alternating magnetic field. A method of measuring the alternating electric field by induction coil based on the principle of electromagnetic induction is put forward. The output voltage of induction coil in measurement circuit is analyzed, and then the time domain signal is converted to frequency domain phase. Finally, the simulation analysis of equivalent input resistance of measurement circuit and the influence of electric field frequency on output voltage of induction coil are given. The experimental results show that this method of measuring alternating electric field using induction coil is feasible.
