When induction motor is started,we see all other electrial
appliances connected on the same supply are dimmed out for
some moment why?
Answer Posted / swarnansu
since the inductive loads are having lagging p.f. so it
draws a huge reactive power which leads to reduce the p.f of
the supply voltage which is also connected to all other
appliances,which leads to dimming out of supply for some time.
