“…From the figure, it becomes known that attaching the sensing head to an existing cable is easy. (2) Application By a field test for the fault location using a 275 kV, 15-kmcable line, it became clear that the maximum location error of the system is less than 50 m, and the locating accuracy is conformed to the required value sufficiently [13]. After the evaluation of the test results, since 2007, the system has been applied practically for 275-kV underground lines of TEPCO.…”

This paper describes the development and applications of a fiber-optic electric current sensing technique with the stable properties and compact, simple, and flexible structure of the sensing device. The special characteristics of the sensors were achieved by use of the special low birefringence fiber as the Faraday-effect sensing element and were also achieved with creation of sensing schemes which matched with the features of the fiber. Making use of the excellent features of the sensing technique, various current monitoring devices and systems were developed and applied practically for the control and maintenance in the electric power facility. In this paper, the design and performance of the sensing devices are introduced first. After that, examples of the application systems practically applied are also introduced, including fault section/point location systems for power transmission cable lines.

SUMMARY Optical current transformers (CTs) have the advantages that they can be made much smaller and lighter than conventional electromagnetic induction transformers by their simple structure, and contribute to improvement of equipment reliability because of their excellent surge resistance performance. The authors consider optical CTs to be next‐generation transformers, and are conducting research and development of optical CTs aiming to apply them to measuring and protection in electric power systems. Specifically, we developed an independent optical CT utilizing basic data on optical CTs accumulated for large‐current characteristics, temperature characteristics, vibration resistance characteristics, and so on. In performance verification, type tests complying with IEC standards, such as short‐time current tests, insulation tests, accuracy tests, and so on, showed good results. This report describes the basic principles and configuration of optical CTs. After that, basic characteristics of optical CTs including the conditions and results of verification tests for dielectric breakdown characteristics of sensor fibers, large‐current characteristics, temperature characteristics, and vibration resistance characteristics are described. Finally, a development outline of the independent optical CT intended for application to all‐digital substations and its type tests results are described. © 2013 Wiley Periodicals, Inc.
