Electrical news and engineering . rface condensers. the condensers with their respective air pumps being placedin the liasement directly under the units which they water is supplied from the Elbow River by trwo5000 gallon per minute, Mather & Piatt centrifugal pumpsat 35 ft. head, driven by 2300 volt motors, and one3500 gallon per minute centrifugal pump built by John In-glis Co., driven by a 2300 volt Swedish General Electricmotor. The condensate from the turbines is pumped through arecorder, and from there flows by gravity to either of twoopen feed water heaters. Feed water is supplied to the boilers through a Ven-turi meter by two Jeansville, 3-stage centrifugal pumpsdriven by Terry steam turbines at 2750 , by oneWorthington vertical duplex pump, size 12 in. by 83^ in. by10 in., and by one Fairbanks Morse vertical duplex 10 in. by 6 in. by 12 in. Distribution Lines Power from the hydro-electric plant is transmitted toCalgary at 55,000 volts, over two separate transmission. lines to the companys terminal station in East Calgary. .\tthis station the current is stepped down to 12,000 volts fordistribution to the citys high tension lines. Power is sup-plied to the city over volt lines as follows:âone lineleading to No. 2 sub-station. Ogden, two lines leading tocentral power station, and a ring main circling the city tosupply the different sub-stations. The central station is alsoconnected to the sub-stations by volt feeders. The electrical controlling equipment at the central sta-tion consists of a 12,000 volt and a 2300 volt bus situatedin the north end of the engine room basement. Each phaseof these buses is placed in a separate concrete compartment,and the outgoing and incoming leads are separated by co:i-crete barriers. Normally the buses work as a complete unit,but it is possible b>* the use of sectionalizing switches tocut out sections of the bus without interrupting the ser-vice. The two buses are conne
