Answer / kareena kapoor

reactive power maintains the profile of voltage along the
line.

Answer / santosh jagale birla cellulosi

Reactive power is an imaginary power. Means its presense is
important for the flow of active power. For example, if you
put beer in a glass fastely, what happens a foam appears at
the top of glass. The beer in liquid form settles at the
bottom of glass. Now what ever foam appear at the top of
glass is called reactive power i.e. imginary power(KVAR),
whatever liquid settled down to bottom of glass is apperent
power OR ACTUAL POWER (KW) and the addition of both means
what the total quantity you see in glass is ACTIVE POWER
(KVA).

Answer / ramesh

reactive power its used creative magnetic field .trmission
line reactive power less then active power(export mode).if
reactive power is higher then active power grid power taken
from generator.

I try to check the three phase voltage in multimeter, in 125A isolator switch incommer. first i touch R phase, and then i touch Y phase using multimeter, the moment i touched, it blasts and that moment i got blindness. multimeter selector position is correct(750V AC MODE AND RED PROBE WASS IN v AND BLACK PROBE WASS IN COM. MODE. COULD ANYBODY GIVE ANSWER FOR THIS TO AVOID FURTHER ACCIDENTS PLEASE?
