The conductor carrying the current to be measured is the one turn primary, sensitivity can be set at 1 volt per ampere or at other desired values. It can also be doubled by looping the conductor through the hole twice. This current sensing transformer can be used for sensing branch circuit overload, switcher feedback and detecting load drop or shutdown. Varying terminating resistance will increase or decrease output voltage/ampere in conductor.
