why when we perform SCC of an alternator we always get a
straight line even when 125% rated current is flown?
Answer Posted / moody
nice question
we got astraight line becas when we make ashort circuit on
the armature winding so only alittle net mmf is produced
from the field and armature reaction so the field current
used not exceeding 20 % of the field current for rated
voltage and in the drawing os o.c.c this region is
astraight " non saturation"
draw the phasor diagram and u will see the answer by ur self
