Requirements that relay protection design should meet
To accomplish the design objectives, four criteria for protection should be considered: fault clearing time; selectivity; sensitivity and reliability (dependability and security). Protective relays and devices have been developed over 100 years ago to provide “last line” 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. For professionals working in utilities, industries, or renewable energy systems, understanding these standards is not optional—it is essential. This document provides recommendations, background and philosophy on relay protection that is not available in M07. The functional requirements of the relay: The most important requisite of the protective relay is reliability since they supervise the circuit for a.
