“…Among magnetoresistance effect components, sensors based on tunnel magnetoresistance (TMR) effect have been used as the fourth generation magnetoresistance sensors in fields such as power grid current measurement and current monitoring [16][17][18][19]. As the fourth generation magnetoresistance sensor based on tunnel magnetoresistance (TMR) effect, it has been applied in fields such as current measurement in power grid and other current monitoring [16][17][18][19]. However, the sensitivity of TMR is temperature dependent with a negative temperature coefficient.…”

“…The measurement of the flowing rail current could then be achieved by using Rogowski coils that ensure a complete rejection of common-mode signals and a more favorable signalto-noise ratio. Another method of rail current measurement that allows train circulation, and can be a semi-permanent installation, is by means of close-up sensors, based on the inductive effect [36], with arrays of such elementary sensors for better reconstruction [37], or alternative methods, such as the Hall or magneto-resistive effect [38].…”
