The incoming lines from Vaca supply abank of three 10,000 K. V. A. transformers,with a fourth transformer held in reserveas a spare, and the voltage is reduced to60,000 and 11,000.

As was the case in the substation build-ing itself, the bus structures and other ap-paratus in the yard have been laid outfor very convenient extension.
