Fig. 7 Protection and control of two incoming feeders using IEDs with standard configuration

F. The two incoming feeders can be connected in parallel by closing the busbar-
sectionalizing breaker. To achive selective overcurrent protection, directional
overcurrent stages are needed. Busbar main and back-up protection for outgoing
feeders is implemented using residual overvoltage protection stages. Phase undervoltage
and overvoltage protection can be used for tripping or just alarming purposes.
