The working principles of MOCT(Magneto–Optical Current Transformer) based on improved dual optical path detection method is studied. The MOCT’s output could be influenced by both the fluctuation of operating wavelength and the error of intersecting angle of optical axis between polarizer and analyzer . Based on IEC 60044-8 standard, the scope of the photosource wavelength and angle error of photic axis are obtained. The results would be useful for researchers and designers working in the MOCT area.
