This chapter provides an overview of overcurrent protection in power distribution systems. The main devices involved are presented, with their characteristics and functionalities. Another important point is about protection theory, which refers to the devices’ performance against faults. Then the methods of selectivity and coordination are discussed, which are used to relate their performance to network characteristics and the relationship between different types of equipment. In addition to exemplify these theories, some didactic examples are given demonstrating their operation.
