Relay protection additional secondary value
Backup protection is a secondary layer of protection that provides additional protection in case the primary protection fails to detect and isolate the fault. Backup protection is designed to cover a wider area than primary protection and is usually applied to less critical parts of. Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 2 Abstract: 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. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A straightforward way of obtaining selective protection is to use time grading. In HV (High Voltage) and MV (Medium Voltage) substations, relay protection safeguards critical assets such as transformers, circuit breakers, and lines. Use the economical SEL-587Z to combine proven high-impedance analog technology with the advantages of microprocessor technology.
