Station Service Transformer Sizing. Therefore, a 75 kva transformer would be selected for this application out of the available standard ratings for a 480 v primary to 208 y/120 v secondary. For hvdc connections, the transformer stations also accommodate the ac/dc converter.
If this message persists, please contact us. Determine the secondary current rating. Sorry for the long load!
A distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.
Automated site maintenance is running. In general, the newly sized transformers were one to two transformer sizes smaller than what was generally specified in the past. Transformer size in kva = 42 kva x 1.25 = 52.5 kva. I need help to sizing the mv cable suitable for the following situation:
