Title: Metering-accuracy fiber optic measurement of transmission-line currents

Abstract

Optical current sensors are gradually evolving from demonstration and prototype units to commercially available stand alone systems. In particular, the electric power industry is eager to exploit the intrinsic high voltage isolation of an optical current sensor`s all-dielectric construction. This distinctive characteristic reduces both the complexity and cost of insulator columns on high voltage lines providing a significant advantage over conventional iron-core technology. Also, the superior bandwidth and dynamic range performance offers the potential for these devices to be implemented as diagnostic tools in a wide range of applications. Currently, bulk glass magneto-optic current transformers and magnetic field concentrators in combination with bulk glass magnetic field sensors seemed to have had the most commercial success. Shortfalls of the bulk optic approach include the need for highly stable assemblies in order to couple light into and out of the optical fibers. Also, their solid glass construction make it difficult and costly to increase the number of optical turns around the conductor. The concentrator systems have bandwidth and dynamic range limitations similar to iron core current transformers and thus do not fully exploit the technical advantages of optical sensors. The all fiber design offers the flexibility of number of turns and shapemore » as well as the performance advantages of high dynamic range and bandwidth.« less
