RECENTLY much engineering thought has been directed toward the use of a-c power systems in very large aircraft.1,2 To permit operation at substantially constant frequency, when generators are driven by accessory drive shafts of main aircraft engines,

THE problem of power-factor correction of resistance-welding machines is of current interest because of their widespread and rapidly growing application. In addition, new and improved methods of capacitor production have diminished the cost of capaci

The studies and analyses presented in this paper provide a rational method for the selection of the optimum buffer reactance and synchronous condenser size to limit flicker-voltage disturbances caused by arc-furnace loads on power systems in those ca
