Most current sensors are based on use of a Hall element positioned in the air gap of a magnetic yoke. They have limited zero stability given by the Hall sensor offset: typical offset drift of a 50 A sensor is 600 [1A in the (0AdC to 70AdC) range. It is twenty times worse ... Si-Fe laminated sheets. DC current transformers work on theanbsp;...
