In this paper a cost effective system design of current transformer (100/5 Ampere) through application of robust design methodology is proposed. The results show that with better performance, the market price of proposed current transformer can be much less than half the price of one of the famous current transformer brand in market. These results are obtained under vast environmental conditions of network frequency and temperature variations of Iran.
