Abstract
Described herein is a self-powered system for detecting a current spike. The current spike is delivered through a current return network that energizes a resonant circuit to produce an alternating electrical output. The output is rectified by a rectifier into direct output that is then transferred to an integrator circuit. The integrator circuit slowly builds to and dissipates from a voltage threshold corresponding to an output transistor. When the output transistor is triggered by the voltage threshold this trigger is communicated to a fault monitoring software that recognizes the current spike.
