Electrical news and engineering . he shape of low equivalent lightning arresters are pro-vided for each underground cable. The two sets of busbars are in turn subdivided by tie switches. Control Equipment.—The arrangement of control andmetering devices is somewhat different from those in thegenerating station, a bench board of black marine finishedslate being provided for the control of the various circuits,a dimimy bus-bar and indicating lamps showing clearly tothe operator the condition of the various switches. Facingthis control desk is an indicating instrument board. Onthis are 3 ammeters for each high tension line, 3 ammetersand one wattmeter for each transformer bank and an am-meter for each feeder of which there are leu in the presentlayout, two volt meters a frequency meter and provisionfor a synchroscope. This bench board is mounted on agallery at the west end of the high tension switch room andat what will be the centre of the completed building. Onthis floor is also mounted tlie local service switch board. Fig. a—Generating Station, Side, Point du Bois. operated by the circuit breakers throws the voltage trans-formers for either set of bus bars onto the feeder wattmeters, so that only one set of voltage transformers isneeded on each bus section.
