guaranteed to deliver rated output with outside-air temperature below 30 F, ao It will be necessary to install supple* menlary gas unit heaters. Each generator connects through a "unit-system" arrangement, consisting of a 14,000-kva 67,200/12,470-v 3-phase oil-insulated self-cooled transformer and 600-amp 69-kv oil circuit breakers of 1,000,000-kve interrupting capacity, to a 66-kv otation bus. To serve aux iliary equipment a 1500-kva 3-phaso 13,200/460-v aakarel-ineulated selfcooled unit transformer is throat-con nected to air-blast circuit-breaker switchgear. Auxiliary 440-v power dis tributes through the load center to motorized units. A transformer simitar to the auxiliary draws from the utility's 12.5-kv distribution system by means o( a disconnect switch for start-up and standby of all four units. The buses are designed to carry 2000 amp continu ously. Permian Basin design aims at the lowest practicable investment cost con sistent with efficient and reliable opera tion. Another objective has been to arrange structures and equipment minimum operating and tnsuiteolabor will be needed. This Is proaby design compactness and care in general and detailed arrangement, Ebaeco Services Incorporated QS rendered engineering and construct services to Texas Electric Sendee on this Permian Basin project as similar, double-unit turbine-geutrs and boiler installation at its WlFalls Station.
