... eoretical work has been done, more or less systematically, on transients, and a great mass of information is thus available in the literature. These transients are more ex- tensively treated in "Theory and Calculation of Transient Elec- tric Phenomena and Oscillations," and in " Electric Discharges, Waves and Impulses, '' and therefore will be omitted in the fol- lowing. However, to some extent, the transients of our theoret- ical literature, still are those of the "phantom circuit," that is, a circuit in which the con ...Chapter 5: Free Oscillations - 73 hit(s)

CHAPTER V. FREE OSCILLATIONS. 28. The general equations of the electric circuit, (50) and (51), contain eight terms: four waves: two main waves and their reflected waves, and each wave consists of a sine term and a cosine term.

...

The frequency of this oscillating discharge depends up ...Chapter 9: Inductive Discharges - 59 hit(s)

In electric circuits of considerable capacity, that is, in extended high potential systems, as long distance transmission lines and underground cable systems, occasionally destructive high potential low frequency surges occur; that is, oscillations of the whole system, of the same character as in the case of localized capacity and inductance discussed in the preceding chapter.

... tion Machines. " D. Hunting of S]rnchronous Machines 106. In induction-motor circuits, instability almost always assumes the form of a steady change, with increasing rapidity, from the unstable condition to a stable condition or to stand- still, etc. Oscillatory instability in induction-motor circuits, as the result of the relation of load to speed and electric supply, is rare. It has been observed, especially in single-phase motors, in cases of considerable oversaturation of the magnetic circuit.
