Kritiese beskouing van voerderbeveiliging met inagname van lynparameters

Abstract

The first part of this study consists of a discussion of transmission line parameters and the dynamic factors that influence them. Different types of impedance relay and their respective philosophies of operation are subsequently mentioned. The calculated line parameters are applied theoretically to impedance relays and the results verified by computer simulation. Finally, conclusions are reached and suggestions made to improve the setting and application of impedance relays on feeders.
