Smart grid puts forward higher requirements for measurement equipments, so optical current transducer (OCT) used in power system possess broad application prospects. In this paper, magnetism gathering technology is applied in the design of OCTs optical structure and the magnetism gathering optical structure based on solenoid coil is proposed. Compared with traditional bulk optical structure, this structure simplifies the optical structure significantly. Results of simulation and field operation indicate that this structure can not only enhance the magnetic field created by the measured current significantly, but also improve the long-term operation stability of OCT.
