QUICK MEASUREMENT PROCEDURE FOR QUALITY FLUX DENSITY CHECKING AT 0.3 A/m IN TOROIDAL CORES

R. Pytlech – R. Rygal – W. Pluta – M. Soiński

   To avoid full magnetic testing new method is describe for quick flux density checking. The aim of the paper is to investigate cores production process and treatment to obtain flux density of min. 5 mT at 0.3 A/m, and to ensure transformation with class accuracy 0.1 or better.

Keywords: magnetic flux density, electrical steel, current transformers, ring specimen method, toroidal cores
