Abstract
A system monitors alternating current and includes a magneto-optical current transducer (MOCT) adapted to modulate an optical signal corresponding to magnitude of the alternating current. Beam splitters are in communication with the MOCT which are in turn connected to respective channels. Each channel includes an LED that is powered by a constant current source.
