Home / Operation and Management of Relay Protection Devices
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. 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. This Modern Power System Protective Relaying training course has been designed to provide a clear and perfect understanding of power system protection schemes and devices, including protection relays, fuses, circuit breakers, and other protective devices. Protection relays are used in power systems to maximize continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilization of the power.
