Tier 5 Health Care Power System

[Mbrooke]

Anyone know how to economically design a system such that each critical area has multiple independent power feeds?

Basically what data centers do but without all the UPSs.

I don't understand the "Break before make" and "Make before break" on the tie breakers.

I think it means you open the sub-main first before closing the tie; close the submain before opening the tie downward respectively.

But in any case the pic is an example for discussion purposes.

Have at least 3x replication for ICUs, ORs, ect.

Thanks.
I thought it was something like that.
Better to ask than to guess which was to be opened first.
There may be some faint lines showing interlocks that are not coming through on my monitor.

Sync check needed between the various UPS distribution. Definitely a challenge economically...

There probably won't be any major UPSs, just the structure of having 3 independent power sources in each critical area.


Regarding economics- I'm guessing the fact only critical loads will transfer between these three branches means basically 3 smaller systems equal in capacity to one large system?
