What This Theme Gathers

Passages involving motors, generators, transformers, reactors, lamps, arc lighting, synchronous systems, short circuits, and power-station apparatus.

Reading Layers

Source Evidence

Use the tables and snippets below to locate Steinmetz passages. Exact wording still needs scan verification before canonical quotation.

Modern Reading Prompt

Use these hits to connect the abstract theory back to the machines and systems Steinmetz was actually engineering.

Interpretive Boundary

Do not lift apparatus passages into purely philosophical claims without preserving their industrial and circuit context.

CHAPTER XIV PHASE CONVERSION AND SINGLE-PHASE GENERATION 126. Any polyphase system can, by mean? of two stationary transformers, be converted into any other polyphase system, and in such conversion, a balanced polyphase system remains balanced, while an unbalanced system converts into a polyphase system of the same balance factor.1 In the conversion between single-phase system and polyphase system, a storage of energy ...

... y storage and return is accomplished by a periodic speed variation, thus only a part of the energy restored, and furthermore, only a part of the structural material (the flywheel, or the rotor of the machine) is moving. Thus assuming that only a quarter of the mass of the mechanical structure (motor, etc.) is revolving, and that the energy storage takes place by a pulsation of speed of per cent., then 1 kva. at 60 cycles would require 600 c.e. of terial, at 40c, Obviously, at the limits of dielectric or magnetic field strength, or at the limits of mechanical speeds, very much larger am ...

... XXXVII QUARTER-PHASE SYSTEM 310. In a three- wire quarter-phase system, or quarter-phase system with common return-wire of both phases, let the two outside terminals and wires be denoted by 1 and 2, the middle wire or common return by 0. It is then, El = E = e.m.f. between 0 and 1 in the generator. Ei = jE = e.m.f. between 0 and 2 in the generator. Let 1 1 and 1 2 = currents in 1 and in 2, 7o = current in 0, Z] and Z2 = impedances of lines 1 and 2, Zo = impedance of line 0, Yi and F2 = admittances of circuits 0 to 1, and 0 to 2, /'i and /'2 = currents in circuits 0 to 1, and 0 t ...

... = — - r The maximum value, which the magnetic field during the transi- tion period can reach, is limited to less than double the final value, as is obvious from the construction of the field. Fig. 19. It is evident herefrom, however, that in apparatus containing rotating fields, as induction motors, polyphase sjaichronous machines, etc., the resultant field may under transient conditions reach nearly double value, and if then it reaches far above magnetic saturation, excessive momentary currents may appear, similar as in starting transformers of high magnetic density. In polyphase rotary ...

In polyphase rotary SINGLE-ENERGY TRANSIENTS. 37 apparatus, however, these momentary starting currents usually are far more limited than in transformers, by the higher stray field (self-inductive reactance), etc., of the apparatus, resulting from the air gap in the ...
