Electrical news and engineering . Kear view of Priston switchboard tributcd at that pressure for street and residenlial lighlingand power purposes. The entire station e(iuipnicnt was furnished by the(. Westinghousc C<inipany, and consists of tliircsingle-phase, 170 kw., 35 cycle, oil-filled, self-cooled trans-formers, the primaries of which may be used with 13,200volts. The street lighting circuit is controlled by a constant current transformer designed for 2,200 volts THE ELECTRICAL NEWS ^ primary. The switcliljuard consists of live panels control-ling the circuits mentioned above and the high-tension cir-cuit. The station switch is a 13,200 volt, type E, oil switch,installed at some distance from the lioard. The otherswitclies are attached to the rear of the board as shown inthe accompanying cut. The following types are used:—residential panel, 2,200 volt, type B.; street lightingpanel, 2,200 volt, type D.; factory power panel, 2,200 Front View of Preston Switchboard type The usual indicating instruments are installedwith each panel. The cuts reproduced herewith show a general view ofthe switchboard, transformers and regulating transformer,as well as the several switches, potential and series trans-formers mounted on the rear of the board. The streetlighting equipment consists of two hundred and fifty 45-watt series tungsten lamps, installed with reflectors on thepoles carrying the different circuits. These are spaced oneor two poles apart. The St. Lawrence River Crossing of the CanadianLight and Power Companys Transmission Lines A power development of the magnitude of that inwhich the Canadian Light & Power is now en-gaged always presents new features of interest to the en-gineer. One of these in this undertaking was the spanningof the St. Lawrence River. This is particularly noteworthybecause of the width of the river and the lateness of theseason during which the work was carried on. The high t
