Fiber-optic voltage and current sensors for distribution systems. Final report
- OPTRA, Inc., Beverly, MA (United States)
A program has been completed which initiated the development of fiber optic based current and voltage sensors for power distribution systems in the 15--35 KV range. The long term goal is to commercialize emerging electro-optical technologies into practical sensor products that provide the capability/cost combination needed to greatly expand the installed distribution system monitoring database. Critical milestones achieved under this program include: market identification, sensor system design, and prototype sensor feasibility demonstration. A market study was performed to determine the level of interest in optical sensors among potential distribution system buyers with the overall conclusion that there is a reasonably sized total annual market for current and voltage sensors with potential for growth. The sensor system was designed to take advantage of many readily available optical components commonly used in the optical communication industry. Bulk optic (as opposed to fiber optic) transducers are used to sense the electric and magnetic field and the optical processing scheme allowed the use of multimode optical fibers to link the sensor head to the processing unit which also contained the low cost laser diode source. Two prototype sensors were designed, built and tested. Although these units did not demonstrate all system specifications, they did prove the feasibility of the sensors. The performance of the voltage and current sensors were sufficient to allow the next phase of the commercialization program to proceed with high confidence of successfully meeting all accuracy and environmental requirements in the next phase.
