Fault Current Limiters and Their Classification

Abstract

In this chapter, various FCLs are classified based on their main components and technology. This classification helps explain how FCLs operate and why they are categorized in a particular group. Then, the classified operations are explained in detail, considering their topology, basic implementation, and fault-limiting procedure. This detailed explanation begins with the most fundamental topologies and progresses to the complicated hybrid FCLs. Furthermore, the fundamental analysis of FCLs presents a basic approach to designing FCLs and provides a deeper understanding of how FCLs limit fault currents. The goal of this section is to understand how different FCLs are designed, operated, and evaluated.
