A commercial office building is to be supplied service at 208Y/120 V from the utility company 12.47 kV distribution feeder (12.47 kV line-to-line and 7.2 kV lineto-neutral). The estimated demand load is 85 kW at 0.9 lagging power factor. Determine the appropriate apparent power rating and voltage rating of the threephase, pad mounted transformer required to serve this load. The transformer is connected delta-grounded wye. Assume the load is continuous and allow a 25% factor for load growth.
