Relay coordination refers to setting protective devices so that the relay closest to the fault operates first, while upstream relays act as backups. The goal is selective tripping—only the faulted
Power System Protective Relays: Principles & Practices
Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of
