What do you do for 120 V lighting and outlets on a corner grounded delta? Use a step-down transformer?

I think between our two radio stations we have had every style of
power delivery out there.

Site A has three phase corner ground.  The site is from the
1930s-1940s and is still like that.  The Nautel runs fine with it.
 Odd, totally uncommon, but it works.

Site B is where it got interesting.

It started it's life as a "Open Delta" service.

Then, around 2005, the new Harris purchased wouldn't run on open
delta, so it was converted to closed Delta.

Then the space was added on to with the new section of the building
getting a separate service with its own electric meter being fed
480/277 with power transformers in the space to convert that to 208
Wye for the smaller stuff that needed it and the 110 volt items.

That's how it sits today.
