This article is devoted to the new electromagnetic sensor design of large direct and alternating currents with expanded functionality for the electro supply devices control and management systems on electrified railways. It’s analyzed that its nonlinear magnetic circuit with longitudinal magnetization based on the magnetization curve approximation. Also it’s shown that developed sensor sensitivity depends on working air gap sizes and modulating magnetic field induction.
