These transformers are employed in connection with alternating-current dynamos.
This pressure is generated by a steam-driven alternating-current generator and is transmitted over the conductors to sub-stations, where by means of step-down transformers, the pressure is dropped to, say, 600 volts alternating current which by rotary converters is turned into direct current for the street mains, for feeders of railways and for charging storage batteries which in turn give out direct current at times of heavy demand.
With enlarged hands at the ends of almost fleshless arms he clutched at the knobs of rheostats and the cranks of transformers, hesitantly, spasmodically, and without ever quite reaching anything. Each time he withdrew his hands quickly as though he had been on the point of touching something very hot. His arms might have been elongated by a lifetime of such aborted movement.
The same explanation is also applicable to the Deptford case, for when the dynamo is direct on, the condenser current is about 10 amperes, and this exerts only a small influence on the strongly magnetized magnets. When transformers are used, the field magnets are weak, while the condenser current rises to 40 amperes. Mr.
"Mart, did you see what I saw, or did I get tight on something without knowing it? That sure burned me up it breaks me right off at the ankles, just to think of it!" Crane walked to the educator in silence. He examined it, felt the changed coils and transformers, and gently shook the new insulating base of the great power-tube.
Tuning coils, sometimes called transmitting inductances and oscillation transformers, are of various types. The simplest kind is a transmitting inductance which consists of 25 or 30 turns of copper wire wound on an insulating tube or frame.
Old Smallways went to his grave under an intricate network of wires and cables, for Bun Hill became not only a sort of minor centre of power distribution the Home Counties Power Distribution Company set up transformers and a generating station close beside the old gas-works but, also a junction on the suburban mono-rail system.
"Kendall Labs Kendall speaking." "This is Superintendent Foster, of the New York Power, Mr. Kendall. We have some trouble just now that we think your operations may be responsible for. The sub-station at North Beaumont blew all the fuses, and threw the breakers at the main station. The men out there said the transformers began howling " "Right you are I'm afraid I did do that.
As each key and meter was wrought and mounted, there were indelibly impressed upon his brain the exact reason for and function of the part, and later, when the control itself was finished and the seemingly interminable task of connecting it up to the output force-bands of the transformers had begun, he had a complete understanding of everything with which he was working, and understood all the means by which the ends he had so long desired were to be attained.
He proposes to transport the city on rails and to change it into a watering-place. The profit, of course, would be enormous. Mr. Smith, captivated by the scheme, bought a half-interest in it. "As you are aware, sir," began applicant No. 3, "by the aid of our solar and terrestrial accumulators and transformers, we are able to make all the seasons the same. I propose to do something better still.
