Abstract

This paper describes two models: a saturable current transformer model (CT) and a wide-band coupling capacitor voltage transformer suitable for real-time transients simulation. By using very efficient network reduction and network synthesis techniques, the operations count for these models is kept to a minimum. The accuracy of the models has been tested in connection with our real-time transients simulator RTNS and compared to conventional EMTP models
