what happen if power factor goss to above unity (one) ? of any electrical system or motor...

Answer / prashanth kumar hg

The power factor in elctrical systems is either a Lagging
one or leading one which is always less than unity.
Lagging power factor is case of induction loads (coils,
motors etc) and leading power factor in case of Capcitive
loads (capacitors).

And the power factor is always unity (1) in case of
Resistive loads (Heaters, Incandascent lamps, Resistors)
and the power factor will never goes more than 1.

Answer / narayanan

Answer 4 is correct . Power factor never goes beyond 1 , theoretically PF=cos PI . SINCE COS has maximum value of 1.so power factor always 1 or less than 1

Answer / p.h.godavary

Answer#4 is OK except that Heaters, Resistors and Lamp filaments, being coils, are not pure non-inductive loads in theory. Hence the power factor (p.f.) can be near unity and not 'always unity'.

With advancement in electronics and control systems, dynamic p.f. control is in practice (in steel rolling mills) to maintain unity p.f. always.

power factor cannot be above unity in any case practicaly
or theorytical........
so relax nothing happen...my frnds...

Answer / shahbaz sahikh

as we know that power factor is the ratio of active power to
the apperent power power factor will greater then unity in
only one case when active power is greater then apperent
power at that time circuit will daamage

Answer / bhuvan sharma

if the power factor will increase more than unity thats mean current will drawn in the machine will be increase therefore due to the increase in current looses will be increase and supposed if we gonna get 80 % power at the o/p dn we get 70-75 %.

what happen if power factor goss to above unity (one) ? of any electrical system or motor...

Answer / venu

suppose if power factor is unity.in case of motors
(induction motors)there will be no relative speed between
the speed of rotating magnetic field and the speed of
motor.which causes slip to zero.so the motor will stop it
will not run
