Part 11

=_Reliability._=—The Light is solely derived from Storage, and is absolutely steady. There is no connection whatever between the Lamp and Moving Machinery.

The Supply is continuous day and night.

=_Economy in Prime Outlay._=—The proportion of Engine Power in use to the power required for maximum supply is only about _one- third_, while any system, if running direct, requires a large portion of the plant to be duplicated.

=_Economy in Working._=—The generating station is only at work a definite number of hours during the daytime, after which period the plant may be let out or utilized for other purposes, such as motive power, &c.

=_Electro Motors_= for all purposes can be driven from the ordinary discharge mains. This is impossible where alternating currents are employed.

=GUARANTEE.=—The E.P.S. Co. undertake to supply all the necessary renewals for the Storage Batteries in use in the above system at the rate of =12=% per annum on the actual first cost of the Batteries.

E.P.S. Accumulators are already in use at the following Central-Stations:—Vienna; Berlin; Cadogan (London); Norwich; Taunton; Leamington; St. Austell; Detroit, U.S.A.; Allentown, U.S.A.; Blenheim, U.S.A.; Haverford, U.S.A.; Delaud, U.S.A.

OPINIONS OF THE PRESS. _The Builder._

“Mr. Hedges points out clearly the risks that are inseparable from slovenly work and incompetent handling, and gives clear directions for carrying the main and branch conductors and the lamp wires, and for calculating the sizes of the various leads according to the number of lights to be worked. He insists very properly that some regular system should be followed, so that it should always be known which is the positive and which the negative wire,—in other words, which wire leads from the machine to the lamps, and which is the return. In addition, however, to showing this by mere position, _i.e._, by placing the positive wire on the left side of the negative if vertical, and under it if horizontal, we should strongly recommend that the insulating covering should be of different colours on the two wires, and thus any accidental displacement would not be of consequence.”

_Revue Internationale de l’Electricité._

“Ce petit livre sans prétention contient une grande quantité de renseignements pratiques. Tous ceux qui s’occupent d’éclairage électrique trouveront grand profit à le consulter.

“Dans les quatre-vingts pages que contient ce travail, l’auteur a su rassembler toutes les indications nécessaires et utiles pour effectuer les installations. Il n’était pas possible de grouper d’une manière plus logique, plus claire et plus concise les règles à suivre pour assurer le bon fonctionnement d’une installation d’éclairage.

“L’auteur s’est étendu surtout sur la description et l’installation des appareils de sùreté, sur la pose des conducteurs et sur les diamètres à leur donner, sur l’essai des circuits, etc....

“Un petit dictionnaire, donnent l’explication des terms techniques, complète d’une manière heureuse ce petit guide qui sera consulté avec autant de profit que bien d’autres ouvrages plus étendus et conçus dans un esprit moins pratique. “AUG. M.”

Useful Information on Electric Lighting. EMBODYING THE RULES OF THE FIRE RISK COMMITTEE AND THE ELECTRIC LIGHTING BILL;

ALSO PLAIN DIRECTIONS FOR THE WORKING OF ELECTRIC LAMPS AND DYNAMO MACHINES.

BY KILLINGWORTH HEDGES, _M.I.C.E., M. Soc. Telegraph Engineers, F.C.S._

_CONTENTS.—Introductory Remarks—The Production of Electricity—The Voltaic Arc—Division of the Electric Light—Machines or Generators—Power required, and Motors—Application of the Electric Light—Choice of a System—Electrical Measurement—Cost of Working—Result of Various Installations—Measurement of Light and Current—Storage of Electricity and Transmission of Power—Conclusion—Useful Tables and Memoranda._

_The Graphic_,

“At the present time, when the question of illumination by electricity is fully under discussion, a third edition of Mr. Killingworth Hedges’ _Useful Information on Electric Lighting_ is doubly welcome. The little work is now fully brought up to date, and gives a plain, straightforwardly written account of the various forms of the arc and incandescent lamps, and, indeed, of the general system of electric lighting. Thus a very fair idea of the principle may be gathered by the general reader, who will find it a welcome companion when visiting the Electrical Exhibition, while the manufacturer in search of a practicable light for his workshop will gain valuable information from the various hints conveyed in its pages. To the scientific student also the work will be exceedingly useful, if only from the handy memoranda and tables in the appendix. _Altogether the book is the best of the kind that we have yet seen_, and we cannot refrain from hoping that Mr. Killingworth Hedges may see fit to bring out a more compendious and detailed work on the subject, with which he is so eminently competent to deal.”
