ABSTRACT:
The secondary winding of a differential current transformer in a ground fault circuit interrupter is short circuited through an electronic switch. The switch is periodically opened to force any secondary current occasioned by the existence of a ground fault to flow through a burden resistor, thereby developing a relatively high amplitude signal voltage thereacross for processing by a signal processor pursuant to initiating circuit interruption.
