All apparatus thereonis standard The switchboard has two generatorand two feeder panels. The breakers and switches,being 1500 volts, are remote mechanical control, theoperating handles passing through to the back of theboard. The circuit breakers are mounted at the topand front of the panels, and the main switches at therear of the board on a separate slate base. The generator breakers are equipped with reversecurrent relays and no-voltage release. The trolleyis sectionalized in front of each substation, each sec-tion being fed by individual feeders from the 1500 voltstation bus. The auxiliary equipment in each substation, be-sides the battery, consists of a 5 kw., 13,200/120 volttransformer for supplying the light and power cir-cuits, and a small motor driven air compressor Exterior Dundee Substation. The substation buildings at Forest Grove andDundee are 60 ft. long by 40 ft. wide and are of re-inforced concrete throughout. The Oswego buildingis 62 ft. long and 62 ft. wide and is divided longi-tudinally into a transformer section and a conversionsection each 31 ft. wide. The transformer section con-sists of two floors, the upper containing the 60,000volt busses, switches, lightning arresters and meteringtransformers and the lightning arresters for the 13,200volt outgoing feeders. The ground floor contains thetwo 1000 kw. lowering transformers, each of whichis set in a separate fireproof compartment. A Kin-near rolling door is provided for the front of eachcompartment; transformers rest on rails and for re-pairs may be slid on to a four-wheel truck that runson a depressed track serving both is provided for a third transformer this spacebeing at present occupied by oil storage tanks and anoil fil
