Answer / tareq harb

I did not get ur idea here but i will answer generally:

When reactive power consumption (inductive loads) increases
the power factor go down, current increases in the system,
voltage will drop in transmission cables and generators
terminals & the wasted unuseful energy will increase as
will.

To over come this problem there are two ways:

- installing capacitors in the load side so this capacitors
could supply the reactive power demanded by the load. the
main disadvantage is output energy from the capacitor
depends on the line voltage in case it drops the VARs
supplied will come down.
capacitor place & value should be carefully choosen to
avoid leading power factor if the capacitors supply more
VARs than the load demand.

- static VAR generatos & compensators will produce VARs
nevertheless line voltage but it is very expensive.

the question why the capacitor installed on the load side??
BCZ reactive power dissipation is very high in transsmition
lines so if u put capacitor in generation side u need to
supply huge amountof reactive power to sully small
inductive loads more over the transmission lines will be
over loaded & over heated as well.

Answer / gopal manda

when reactive power is input in a device, then power factor
will be change.because reactive power is two type,inductive
reactive power,capacitive reactive power.

Answer / subhrendu nath

Reactive power is unused power,when it enters the system it
damages the system and develop harmonics.

Answer / vinod

reactive power developing when electrical energy is
coverting another energy through flux, reactive power is
more current will be more for the same active power so we
canot utalise capacity of the generator, t/f, cable etc
