Answer / abdurrahim

Reactive power is part of Apparent power(KVA) which is
useless,oscillation between source to user.And return to
source.

To calculate reactive power,It is a sine factor of the
apparent power.

Answer / kvk surya

reactive power is some part of apparent power which is
depend on power phase angle between voltage and current

Answer / rama krishna

Power is defined as the rate of flow of energy past a given
point. In alternating current circuits, energy storage
elements such as inductance and capacitance may result in
periodic reversals of the direction of energy flow. The
portion of power flow that, averaged over a complete cycle
of the AC waveform, results in net transfer of energy in one
direction is known as real power. The portion of power flow
due to stored energy, which returns to the source in each
cycle, is known as reactive power.

Answer / ghanshyam singh

satisfied with RAMA KRISHNA, the power which is returned to the supply is called the reactive power
actual power consumed is active power while total of both these is apparent power

Answer / p.thileepan

reactive power is utilised to produce electric n magnetic
field. . ,wer as active power is used to produce torque n
rotations

Answer / kn

Reactive power is not a working power it stored power in the
form of magnetic field and it is also opposing power

Answer / keshab nath kundu

reactive power is required for producing magnetic field in
motor type load. .

Answer / kotha venkatesh

reactive power= activepower/apparentpower

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
