| TEXT | It is fitted on the same system, and differs very little from those previously described. There are three alternating-current machines, separately excited, of 80,000 watts (40 amperes x 2.000 volts) each, which are directly coupled to horizontal engines running at a speed of 250 revolutions per minute. The exciting dynamos are driven by belting from the main engines ; two of these dynamos are sufficient to excite the three alternators, which are coupled in parallel. The boilers are of the Babcock-Wilcox type. The number of Edison lamps, sixteen candle-power, fixed this year was about 2000, of which 1900 are often all lighted at the same time. The service commences each day one hour before sunset, and ceases one hour before sunrise. |
