| Abstract: | The error of the current transducer is analyzed. A type of low current transducer with cored structure and high accuracy is described which is specially designed for on line monitoring of high voltage apparatus. The circuit in the transducer can track the variation of magnetizing current and compensate it by single chip processor systems automatically to assure the magnetic core working in "zero flux" condition. The test of the current transducer shows that the design gets satisfactory results. |
