how system voltage affect the power factor or vice-versa.

Answer / ashish
voltage does not affect to power factor.
p=vicos(phi)
v is constant and Icos(phi) is variable. I depend on the
load. Hence if i increase than power factor decrese and
vice versa.

In electrical engineering, particularly power engineering,
voltage regulation is the ability of a system to provide
near constant voltage over a wide range of load
conditions..if increase/decrease of
loadcurrent/powerfactor,-ve or +ve voltage regulation
occur..so system receving end voltage may vary.

PF is purely depends on the load. If the connected load is
more inductive then it requires potential difference to
store the energy in form of magnectic flux which is not
useful work to load. Hence the voltage lags behind the
current until the inductance is fully stored.
If more inductance leads to more lagging leads to (cos
<phi>) will be low hence voltage will drop more, since the
actual voltage spiltted for magnectising and work done.
Appropirately current will raise.
