Ideal Power factor is 1.
It is ratio of real power(measured in watts) flowing to the
load to apparent power(measured in VA). It ranges between 0
to 1.

P.F. is a measure of the degree to which a given load
matches to that of a pure resistance.

P.F.=1 if load is purely resistive.
P.F.=0 if load is inductive or capacitive or both.

For RL-circuit P.F. is between 0&1.(lagging)
For RC-circuit P.F. is between 0&1.(leading).

we have consol make 3 phase servo stabilizer for cnc m/c. while installing the earth neutral voltage is 1.7 volts at stbilizer off condition and when stabilizer get on en voltage reaches 4.8 volts (new earthing is done and neutral is helthy condition all phase to neutral volts 440,442,441 v)why this happen.solution for cause.
