hello there
i am doing a assignment about transformer overload by using pic microcontroller (pic16f877A) and i donot know what type of sensors i need to use for sensing the overload and over current rating ?
if any buddy knows about plz do let me know thanks in advance
you can use current transformer for current sencing in microcontroller you can program the value on which you want to over load.
or you can connect over-current relay with it has switch N.O(normally open) and N.C (NORMALLY CLOSE) YOU CAN USE These
switch for over over load
