Application of magneto-optic effects to measurements of currents in the environment of medium and high voltages

The paper presents results of investigations relating application of an optical sensor to the measurement of current in the environment of medium and high voltages. In the investigations was used optical fibre as the optical sensor of the magnetic field in shape of the optical fibre coil. Investigated of the magnetic field. The magnetic field source was the current (I-max = 11 kA) as the effect of discharging of capacitor bank (UBKmax = 11 kV). The influence of design of an optical sensor on his metrological properties was analysed on the basis of the results of investigations and the existing state of knowledge.
