Abstract

This work presents a system for measuring magnetic field intensity. The idea of measurements is based on the influence of an external magnetic field on the polarization state of single-mode light propagated along optical fibers. In the paper, some experimental results of test investigations for the measurements of the magnetic field of high intensity are presented. The ultimate aim of the investigation outlined below is to work out magnetic field intensity sensors which, together with optical fiber temperature sensors and electric field intensity sensors, will make it possible, in the nearest future, to entirely monitor the operation of electromagnetic power units such as, e.g., high voltage power transformers.
