All relay protections in the power supply system

Home / All relay protections in the power supply system

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. 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. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to.
