Does anyone know where can I find the x/r ratio of a 50 kVA pole mounted transformer on the internet?

 

Christina... of course the best data comes from the manufacturer.

If unavailable, then go with an IEEE Standard such as 141, 241, or 551. Also contact transformer manufacturers.

If you need a number quickly, then use 3.00 if unit is three-phsse, and 2.00 if single-phase.
