im trying to make a clamp meter to measure current (ac). the sensor is going to consist of a toroidal core wound with copper. the current carrying wire will pass through the core, inducing a current in the winding. i need some help on the inductor design. what type of toroid, what size, type of ferrite, how many turns, wire type, turn spacing.....
the current that i will be sensing will be the mains coming into my house. 240V, AC, 50Hz, 0.1 - 50 amps.
thanks for any help
