Answer / shiva

power factor is cosine angle of voltage & current in vector diagram,& is ratio of real power to apparent power.. we maintain in our organisation as installation of capacitor bank. its valve in between 0.95 to .99. but valve of p.f. below the 0.9 & above 1.0 organisation get penalty charges as per Msedcl act.. maintaining p.f. means keeping resistance of circuit unity.or balance the resistance of inductive load to resistative load in circuit by capacitance load.

Answer / n nagaraju

0.8 TO 0.95
power factor is the ratio of real power to apparent power

Answer / nithyanandam

Power factor in most industries are 0.93 to 0.99.....

Answer / anil

for ideal power system, power factor is unity(1),
but practcally it is very difficult to archive. but this
value is effected by reactive load.
Power is generated at power factor of .8 to .85 .
so we can maintain the power factor at .8 to .85

Answer / selvan

we are maintaining the PF in factory at unity without the
help of APFC unit.we miantain the PF below 0.95 lag for
avoid EB penalty.

Answer / shiraz khan

yes, it is true that we can't maintain the power factor
nearer to 1, but in CAPACITIVE or in the case of RESISTIVE
load it is possible that we can maintain the power factor
from 0.9 to 0.96. And normally in our homes we can easily
maintain the power factor, because we didn't normally uses
the 3 phase inductive motors, or any othe heavy inductive
load like as in factories.

Answer / dev123kk

Well we keep it to as close as .9
.9 bcoz if it gets to 1 then sudden change of pf will make it more than 1 and this is harmful for our system

Answer / bhavesh

.999

Answer / surya_tech4u

In cement industry maintain pf near by unity if power taken from SEB by using APFC for LT load and bus capacitor for HV system. Monthly average pf is .991 to .995.SEB generally offer insetive of 1% above .97 pf in some state.
But if CPP is there maintaining .95 to .98.
