1. SST-1D transformer differential trip and undervoltage trip are included in this analysis.

2. Load Shed (94F3): Breaker ED08 is open so load shed signal is not of concern.

3. LOSP and ESFAS Sequencer (R-16, R6F, XF): Spurious sequencer signals can result in spurious close of alternate supply breaker ED08, thus dependencies are required.

Comments

1. 125 VDC control power is not needed to maintain breakers in desired position. However, it is required for Breaker ED02 to maintain over current protection.

2. Mechanical interlock prevents spurious close of Breaker ED12, so no cables included.

3. Breaker ED08 is analyzed for spurious close to preclude paralleling 3-phase power out of phase.

4. Bus bar connection between SST-1D and main bus is local to switchgear.
