THEMABeschreibung
TEXTGevelsberg, a town of about 10.000 inhabitants, situated in the valley of the Ennepe between Elberfeld and Hagen, is not suitably adapted for an electric light project, as it extends for a distance of four miles, and is very narrow, two-thirds of the whole town coneisting of a single street, the Hagenerstrasse. This situation naturally demanded a comparatively large expenditure for copper mains, which were arranged so that the loss of electromotive force was 10 volts in the feeders and two volts in the distribution mains. The plant, which was erected in November, 1890, was originally designed for an equivalent of 4000 16 c.p. lamps, machines being first put up sufficient for 1120 lamps burning simultaneously. For this there were erected two Kuhn condensing engines of 60 nominal H.P. each, and three shunt-wound dynamos, one of 40.000 watts, the others of 20.000 watts each; these were used with two sets (66 each) of Tudor accumulators, of 700 ampere-hour capacity and 140 amperes maximum The small dynamos can, if necessary, be loaded up to 30,000 watts. The two accumulators are charged in parallel by the three dynamos; the total voltage cells varies from 320 to 240 volts during discharge. The 1120 lamps of 16 c.p. 560 amperes at 120 volts or 67.200 watts, including the loss in the mains. The batteries will give 140 amperes at 240 volts = 33.600 watts, their capacity being ampere-hours; the output of the three dynamos is 80.000 watts. There is, therefore, a reserve power of 100 per cent, one engine being sufficient. The dynamos and accumulators together will run 2000 lamps. The distribution circuits are arranged on the three-wire system ; the current is taken by means of four feeders to six distributing points (the total fall of potential at full load being 10 volts), to the supply mains, in which there is a maximum loss of two volts. All the mains are run overhead on wooden poles, which are impregnated with corrosive sublimate as a protection against rot. For street lighting, 50 candle-power glow lamps are used in series. The street lighting can be arranged to suit the different loads at the distributing points; but it is intended to put the four glow-lamp circuits in series, for which purpose a continuous-current transformer will be used to raise the voltage from i lO to 440. Besides these lamps, there are for public lighting of squares, etc., eight Essberger arc lamps. The charging current for the accumulators is regulated by hand with two multiple switches, the discharge being controlled by two automatic switches; three other automatic switches prevent the reversal of the current from the battery during charging. Each feeder is provided with an ammeter and testing wires, run from the distributing boxes to the switch-board, for regulating the electromotive force at the junction with the mains, which is effected by means of resistances, the board being so arranged that the connections at the back are easily got at The maximum
distance of any lamp is about four and a quarter miles ; about 28 tons of copper were employed for the mains. There are at present about 1500 glow lamps and 16 arcs. The charge per lamp-hour (16 candle-power) is one halfpenny, with reduction for large supplies. During the daytime motors are supplied, of which there are now many working; for these the price for current has been considerably reduced. The charging of the accumulators is commenced in the winter at half-past two, in the summer at a suitably later hour; on many days there is no charging required. The machines are run until 11 o'clock. In the winter the employes do not have to work more than 10 hours; the staff consists of a manager, fitter, mechanic, and a stoker. The cost of the undertaking has been as follows:
Engine house, including foundations, reservoir, chimney and preparations for the boiler 2250 pounds
Steam engine with erection 900 pounds
Boiler 650 pounds
Pumps, pipes, &c 350 pounds
Dynamos 700 pounds
Switch-board 350 pounds
Accumulator with erection 1400 pounds
Cables 2250 pounds
Street lighting 350 pounds
Telegraph poles and insulators 300 pounds
Erection 400 pounds
Total: 9900 pounds
It should be stated that the first cost of meters and electro-motors was defrayed by the town, the consumers now paying a rent for them.
