Abstract

Based on the analysis of the principle of residual current device (RCD), the impact of sensitivity and unbalance response on the characteristics of residual current transformer (RCT) are discussed in detail. And a kind of RCT is designed by using analytical calculation and numerical simulation methods. Finally, a kind of RCD is developed in this paper. Experimental results show that the designed RCD is of good performance, thus the feasibility of the design is verified.
