Relay Protection Processing and Analysis
Standardize procedures for setting changes, testing, and documentation to maintain high system protection integrity. 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 the system continue to run under normal conditions. Three categories of solutions are discussed: 1) relay performance evaluation. Electrical systems usually use fuses and circuit breakers to protect electrical equipment such as cables, transformers, motors, and other components.
