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.

We have 11kV/110V three phase indoor potential transformer in 66/11kV Sub-station, where the failure of PT is frequently happening and the rating of the PT is 0.2 class accuracy, with primary star and seconday (two cores) star connected. Some experts has suggested to not to connect the PT Primary neutral to the ground because when transformer neutal NCT connection is loose; the faulty current will flow through the PT primary neutral, resulting into failure of PT. My question is: Is it necessary to remove the primary neutral connection of the PT from ground? if not, what would be the reason for failure of PT. Please guide me.
