reactive power is a burden on system if it is allowed to
increase pf falls for this more amount of power is drawn
from supply so it is better to keep it as less as possible.

Answer / pushpak mistry

It is component of electrical power cause lower power
factor and drawing more current to give same output of
applications in terms of power.
Due to the higher reactive component in transmission and
distrubution, power loss become more in terms of
transmission line losses.
To reduce the transmit and distribution loss we have to
use higher size of conductor to transmt same power

Answer / rakesh patel

Reactive power is also known as wattless power. it means with help of this power load can't develop any type of output.
so the main role of reactive power in the system is to just push up the active power upto the loads.if value of the reactive power in the system is less to its level, amount of active power is decrease to its rated value. it means rated valtage can't be supplied to the load side and whole system is totally ustable. and if this type of condition is to be continue for some time,blackout also should be possible.

How much allowable difference current between on three phases Dear sir, We have a 1870 KW HT motor, 11 Kv supply,FLA-120A,2870 rpm,2-pole squirrel cage induction Motor.And stator is connected in star connection with Liquid resistance stater to limit the starting current.It has coupled with Centrifugal air compressor.My question is it is loading 73% of FLA taking R-phase 86.7 A, Y-phase-85.4A,B-phase- 78.3A.why the B phase current is that much of difference.Is it allowable, or any one tell me how much allowable current.If any method to calculate.
