E形カットコアを用いた限流素子の特性解析

抄録

Recently, the fault current limiters (FCLs) have become a hot topic in relation to the reliable operation of power supply. Authors reported the characteristics of an FCL using a permanent magnet and a C-type core. In this paper, the characteristics of a FCL using the an E-type core are investigated by the use of numerical analysis, taking account of the eddy current effect. Numerical analysis was performed on the core dimension ratios of the FCL.
The results, clearly showed that the characteristics were strongly influenced by the dimension ratios of the core. The experimental results show a reasonable agreement with the analytical results.
