Abstract :
AC magnetic fields due to bus-bar currents are analyzed to design a three-phase optical current transformer arranged longitudinally. The optical current transformer with a single or double shield structure is studied in order to reduce mutual interference of magnetic fields due to three-phase transmission currents and an additional field induced by eddy currents
