FDR-W-IL LOGIC SCHEME
Logic scheme FDR-W-IL is intended for use on feeder breakers to provide overcurrent protection, breaker
failure protection, reclosing, and control functions required for typical feeders in nondirectional overcurrent
protection applications. When used with other programmable relays using BUS and BACKUP logic
schemes, FDR-W-IL logic provides protection when the feeder relay is out of service. Basler Electric
protective relays that incorporate a BUS and BACKUP logic scheme are the BE1-851 Overcurrent
Protection System, the BE1-851E Enhanced Overcurrent Protection System, the BE1-951 Overcurrent
Protection System, the BE1-1051 Overcurrent Protection System, the BE1-CDS220/240 Current
Differential Systems, and the BE1-IPS100 Intertie Protection System. Complete overcurrent protection for
the transformers, bus, and feeders in radial system substation applications can be achieved by combining
these devices.
