Substation transformer
Substation transformer
(OP)
We will be installing a 2 MVA 23KV/480V delta-wye 3 phase oil-filled indoor substation transformer. The catalog shows the six terminals on the HV side. They call it loop fed. Can somebody elaborate on this.
Thanks.

Imagine a group of these transformers wired in series with both ends fed from utility feeders. Any section of cable or any transformer can be taken out of service without a power outage on the other sections.

The other choice is called "radial" fed. Only one set of lugs. rcwilson is describing two radial-feed connections with a selector switch.
