Transient Fault Limiters

Abstract

This chapter introduces the causes of transient currents, including lightning strikes, arc faults, and capacitor switching. These transient events’ timing and waveform characteristics are studied in detail, and their nature is referenced. Next, their effects on power system equipment are introduced, followed by an overview and study of conventional series limiters. The main highlighted transient limiters in this chapter are series resistive and inductive limiters configured as FCLs. Finally, the different categories of transient limiters are classified, their main features are explained and compared, and their performance is discussed. The chapter covers analysis, topological logic, simulation, and experimental components.
