When the need arises to correct for poor power factor in an
AC power system, you probably won't have the luxury of
knowing the load's exact inductance in henrys to use for
your calculations. You may be fortunate enough to have an
instrument called a power factor meter to tell you what the
power factor is (a number between 0 and 1), and the
apparent power (which can be figured by taking a voltmeter
reading in volts and multiplying by an ammeter reading in
amps). In less favorable circumstances you may have to use
an oscilloscope to compare voltage and current waveforms,
measuring phase shift in degrees and calculating power
factor by the cosine of that phase shift.

There are various method to improve power factor. but main
mathod is to connected capacitor bank. we can calculate the
capacity of capacitor by this formula
KVAr = KW (tan1 -tan 2)

1 . bank of capacitor used
2. induction motor use

Answer / vinamra
if our load is inductive then with using the capacitor we
can improve the pf but if our load is capacitive then
connecting the capacitor our pf will be more poor.means if
pf is lagging then capacitor improve our pf.
