nal circuit is increased or diminished. The arma-ture being kept at a constant speed of rotation, in a con-stant field of force, by the engine, or other source of power,it will impress upon the circuit a constant voltage. Thisapplies of course to an accurately arranged winding. Over… … Fig. 459 CIRCUITS IN A COMPOUND DYNAMO stant voltage is required, not at the generating plant, butin the heart of the district several miles distant. In anover-compounded dynamo the series coil is given a certainnumber of turns in proportion to the turns in the highresistance shunt coil, and the…
