Abstract :
The application of R, S, T components to solve faults in power systems and transient unbalances in power networks has been attempted, to simplify the problems to a greater extent than other components, such as Clarke´s or Concordia´s components. However, these attempts were not completely successful, because the equivalent circuits developed to represent various types of faults did not completely eliminate the use of isolating transformers, which was an objection to a study of the above problems in a network analyser. The introduction of isolating transformers placed certain limitations in representating power systems under changing fault conditions in a transient analysis. It is the purpose of the paper to introduce the modified equivalent circuits in such a way that they completely eliminate the use of isolating transformers, without any need to modify the original equivalent circuits. A systematic analytical approach is also developed for the determination of the transient-recovery voltage characteristics, by illustrating the various steps with a typical fault.
