WHY WE NEED TO IMPROVE POWER FACTOR?


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.

  1. Hi there! glad to drop by your page and found these very interesting and informative stuff. Thanks for sharing, keep it up!
    - 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.
