Claim 18:
19. A monitoring system comprising:
two or more power grid component monitors for one or more components of a power grid transmission and distribution system, each power grid component monitor comprising a plurality of optical sensors disposed on one or more optical fibers, the optical sensors configured to sense parameters of the power grid component, each optical sensor disposed at a location within or on the power grid component and configured to sense a power grid component parameter that is different from a power grid component parameter sensed by at least one other sensor of the plurality of optical sensors;
one or more detector units, each detector unit configured to convert optical signals of the optical sensors of a corresponding power grid component monitor to electrical signals representative of the sensed power grid component parameters;
shared control circuitry communicatively coupled to each of the power grid component monitors, wherein the control circuitry includes the detection units and the detector units are communicatively coupled to each power grid component monitor by an optical communication channel, wherein the optical communication channel includes an optical sensor configured to detect signal anomalies not attributable to transformer parameters; and
at least one optical coupler disposed between the one or more optical fibers and the detector units, the optical coupler configured to spatially disperse optical signals from the optical sensors according to wavelength.
