ABSTRACT:
In a power distribution system, in order to maximize efficiency and to provide protection in the event of a lightning strike or other transient, a fiber optic drive is utilized to transmit measured parameter signals through a fiber optic link to a control system. The fiber optic drive is powered only in timed, short bursts at ten second to ten minute intervals with a power supply that capacitively draws small amounts of energy over the long intervals and energizes the drive with accumulated high power pulses.
