Secondary Selective Substations are substations that having two busses, each supplied by a normally-closed incoming line circuit breaker and connected together by a normally-open bus tie circuit breaker. Although the name is derived from designs utilizing two transformers, the design is applicable (with appropriate functional deletions) to dual-fed substations without transformers.
