lling on the section containing thehot oil. This building also contains provision for switching the old30,000-volt, 80-mile transmission line, fed by the Santa Ana andMill Creek plants, with its various branches and all the 15,000volt distribution around Los Angeles. The arrangement of thevarious circuit bus-bars, oil switches, and the transformers is shownin the accompanying diagram. All switches and circuits are con-trolled from a 12-panel switchboard on the gallery of the turbine-room, which is equipped with the necessary control switches andinstruments for the 60,000-, 30,000-, 15,000-, and 2,300-volt buses. All bus-bar wiring connections to the transformers and theoutgoing circuits are carried in ducts. In the new portion of thestation these are filled with 15,000-volt leaded paper cables of 211,-ooo-cm. cross-section, with the exception of those for the turbo-generator, which has 400,000-cm. cables. There were installed in the steam end of this plant during KERN RIVER PLANT 3°9

When it became nec-essary to order an extension for the plant, in 1905, larger-size ap-paratus was determined upon throughout. An additional 5,250H.P. in 750-H.P. units was installed in the boiler-room. The turbine installation in the new plant consists of a single6,000-K.W. turbo-alternator, with condensing equipment. Thisunit is four-stage, single-flow, and is operated at from 27j-inchto28-inch vacuum. Thus far loads up to 10,000 K.W. have beencarried on the machine without any indication of its maximumload being approached. The generator is wound for 16,500 volts, star connected, andis run with grounded neutral on the 50-cycle distribution of thecompany. The generator operates perfectly and runs in mul-tiple with the main system without causing any disturbance what-ever.
