Current Measuring

Current measuring high-precision methods and devices are one of the most important modern engineering development lines in optimal energy consumption sphere. However, there are a few small-sized instruments which allow conducting precision measurements without breaking the circuit. This paper presents information about conducted Faraday Effect research and general construction of the simple fiber optic current sensor (FOCS). Researched sensor conception is used in prototype which is developing by team of laboratory number 63 of National Research Tomsk Polytechnic University Nondestructive Testing Institute. Required tests and accuracy analysis were conducted. Research results confirm that fiber optic current sensors provide high-precision measurement and proposed methodic is effective.

AbstractAlthough discovered over 150 years ago, it was not until the 1970's that materials were developed that enabled magneto-optic (Faraday) effect devices of practical sizes. These developments are: magneto-optic materials with high Verdet constants, and the rare-earth magnet materials, capable of extremely high magnetic fields.The magneto-optic effect has enabled development of equipment used in diverse laser applications, from industrial use to fiber-optic telecommunications.The principle of operation of optical isolators and circulators is described herein, as well as descriptions of critical components in such equipment, such as the polarizers and the magnets.
