Home / Overall Requirements for Relay Protection Management
This presentation reviews the established principles and the advanced aspects of the selection and application of protective relays in the overall protection system, multifunctional numerical devices application for power distribution and industrial systems, and addresses some. 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 example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. This document provides recommendations, background and philosophy on relay protection that is not available in M07. It is reshaping traditional grid architecture and making way for more flexible, efficient and.
