Abstract

this paper devises a computer-aided program to design an optimized Current Transformer (CT) not only fulfilling the basic requirements of the user/client but also presents the most economical design. In the first step, basic equations for designing the CT have been set up and a computer program has been developed. Then a numerical optimizing technique i.e. pattern search has been used for determining the most economical design for a certain rating of a CT. To evaluate the workability and practicability, a CT has been designed and manufactured using the results obtained from the program. The results of this work have been then compared with the locally manufactured CT of same rating. Computer application has been developed using MS Excel with background coding in Visual Basic (VB).
