Some of
the benefits of improving your power factor are:
_ Your
utility bill will be smaller. Low power factor requires an increase in the
electric utility’s transmission and distribution capacity in order to handle
the reactive power component caused by inductive loads. Utilities usually
charge large customers with power factors less than about 0.95 an additional
fee. You can avoid this additional fee by increasing your power factor.
_ Your
internal electrical system’s capacity will increase. Uncorrected power factor
will cause increased losses in your electrical distribution system and limit
capacity for expansion.
_ Voltage
drop at the point of use will be reduced (i.e. improved). Voltages below
equipment rating will cause reduced efficiency, increased current, and reduced
starting torque in motors. Under-voltage reduces the load motors can carry
without overheating or stalling. Undervoltage also reduces output from lighting
and resistance heating equipment.
Hi there! glad to drop by your page and found these very interesting and informative stuff. Thanks for sharing, keep it up!
ReplyDelete- p-f curve or P-F interval seems like a simple concept, but it is often misunderstood. The P-F Curve is often misunderstood because users take for granted that point "P" (the potential failure) has already been clearly defined.
