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
BE1-951 Overcurrent Protection System, and the BE1-CDS Current Differential System. Complete
overcurrent protection for the transformers, bus, and feeders in radial system substation applications can
be achieved by combining these devices.
The components of FDR-W-IL logic are summarized in Tables 8-13, 8-14, 8-15, and 8-16. A diagram of
FDR-W-IL logic is shown in Figure 8-7. Figure 8-8 shows a one-line drawing for the FDR-W-IL logic scheme.
Normal Operation - Control
The virtual breaker control switch (101) is programmed to provide manual trip and close control of the
breaker. Manual breaker control can be achieved by using the front panel HMI or by entering ASCII
commands through the communication ports. Control functions of this logic scheme use both traditional
contact sensing inputs and virtual switches. Virtual switches that are not needed may simply go unused. The
contact sensing inputs can be freed up for other uses by utilizing the virtual switches for other control
functions.
