Has anyone ever paralleled 13.8kv utility feeders onto a common buss inside of main switchgear?
I have a main-tie-main lineup that will automatically (open transition) transfer to 1 utility source if the 2nd source is lost. Because of the critical loads involved, the customer wants to be able to go back to "normal" mode (2 utility sources) via a closed transition.
We will be installing sync-check relay's to ensure the sources are in phase, and we have the utilities permission to do this, but I wanted to get a second and third opinion.
Do you see any issues with this? How can expect the downstream loads to react to a closed transition? In theory I would expect there not to be a hiccup.
