TIME DIVISION MULTIPLEXED DETECTOR FOR A MAGNETO-OPTICAL CURRENT TRANSDUCER

摘要

A system monitors alternating current and includes a magneto-optical curr ent transducer (MOCT) adapted to modulate an optical signal corresponding to magnitude of the alternating current. Beam splitters (14a, 14b) are in comm unication with the MOCT (12) which are in turn connected to respective chann els (16a, ISb). Each channel includes an LED that is powered by a constant c urrent source.
