ABSTRACT:
A time division multiplexed optical voltage measuring system includes an optical voltage sensing system module including, (i) a plurality of optical sensors where each sensor is responsive to an input interrogation light wave, and (ii) one or more optical outputs affected by sensed electric field thereat. The optical voltage sensing system module includes an optical circuit arrangement having (i) an input for receiving a module specific pulsed light wave derived from a primary pulsed light wave from a remote light source, and (ii) arranged such that each of the plurality of optical sensors receives an interrogation pulsed light wave. The optical circuit arrangement of the optical voltage sensing system module further includes at least one optical wave combiner for combining like-kind of outputs from all of the plurality of optical sensors. The optical circuit is arranged such that the pulsed light waves from the outputs of different optical sensors arrive at the optical wave combiner at differing times. In turn, the output of the combiner is passed to a detector and signal processor at a remote location for signal processing, and providing a measurement of the voltage intended to be measured. In a specific embodiment, each voltage sensing modules is arranged integral with a high voltage insulator column of a multi-phase power line system.
