Abstract

A zero-flux current sensor to be used in International Thermonuclear Experimental Reactor for large DC current measurement is researched and developed. A magnetic flux equilibrium equation based on linearity assumption is introduced to predict its operating parameters. The analysis is done by 3D finite element method and greatly simplified with the help of the sensor’s characteristic matrix. Corresponding experimental tests are also performed on a prototype and the results fit very well with the computed ones. And the sensor’s measurement accuracy and compatibility against external field noise have also been proved by the test results.
