Dry Type Transformer
(OP)
Ihave a dry type 3? distribution tranformer with the following specs:
45 KVA
HV: 208? V
LV: 220Y/127 V
How do you get 208V Delta? Is this just the three phases of 208Y/120 V brought in without the neutral? What would be the typical application of such a small voltage increase? Would this be considered an isolation transformer?

The 220Y/120 V would be more friendly to motors than 208 volts.
This could be considered an isolation transformer.

I remember seeing 220V 3-phase motors and equipment in plants built in the 1940's, still operating 30 years later.
