A 3-phase, star connected, 10 kVA, 380 V, salient pole alternator with direct and quadrature axis
reactances of 15 and 8 0/ph respectively, delivers full-load current at 0.8 power factor lagging.
Neglect the armature resistance. Determine the following: (a) The load angle, (b) The direct axis and
quadrature axis components of armature current, (c) E.M.F induced voltage of the alternator,
(d) The voltage regulation, and (e) The developed power by the alternator?
A 2000 kVA,Y- connected alternator gives an open circuit line voltage of 3.3 kV for a field current of
65 A. For same field current the short circuit current is being equal to full load current. Calculate the full
load voltage regulation at both 0.8 lagging p.f. and unity p.f., neglect armature resistance?

- How can I design a socket for a trolley headlight? What parameters should I measure? The only thing I have is the headlight itself, and I don’t have any information about its power, current, or voltage rating. The power source is 120 V, and my goal is simply to get the headlight to turn on.I’m not sure where to start or what to measure. Any recommendations would be greatly appreciated!arrow_forwardFigure 2 3) *** The circuit of Figure 3 is designed with W/L = 20/0.18, λ= 0, and ID = 0.25 mA.
