Why voltage regulation of an alternator is negative for a leading power factor?
Answer Posted / arijeet chakraborty
In case of leading load that means capacitive load, the effect of armature flux on main field flux is magnetising i.e, the armature flux is adding up with the main field flux. Since it is adding up, the total induced emf(V) will also be more than the induced emf at no load(E).
Therefore voltage regulation= -ve
