Relay protection interface settings
This manual presents the steps for configuring IEC 61850 communication in Bulletin 857 and 865 protection relays. Configuration tool programs are provided by Rockwell. Protection relays employ a wide range of configurable parameters to identify defects & trip the breaker in a controlled & selected manner. Understanding each setting facilitates proper relay coordination. They are intended to quickly identify a fault and isolate it so the balance of the system. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. The Electric Power Research Institute (EPRI) roadmap reports, Roadmap for the Next Generation Protective Devices (1017774) and Current State Assessment: Next Generation Relays (1017773) forecast that as protection equipment and systems continuously evolve in the more feature-rich and sophisticated.

The meaning of k in relay protection
The K factor (or zero-sequence compensation factor) adjusts the measured impedance for the phase-to-ground fault loop by accounting for the contribution of zero-sequence currents. Without proper. nterrupting current rating for high-voltage circuit breakers. The paper teaches how the decaying dc component in the asymmetrical fault current affects the breaker, and it explains how the X/R ratio and the relay perating time affect the asymmetrical current breaker rating. Countries using European standards started out using IEC 60750, Item designation in electrotechnology. It does not prevent or delay the type KD relay from tripping on phase-to-phase faults within its protective.
