By optimizing your energy use you can:
1. Capacitors
Power factor correction capacitors are the most common method of correcting power factor. They can be:
2. Controlling capacitors
A controller provides automatic switching of capacitor units and maintains the power factor level under any changes in operation or load.
3. Adjusting existing capacitors
Existing capacitors may be correctly sized but incorrectly controlled, leading to poor overall power factor. Blown protection fuses on capacitors take the capacitor off-line.
Looking at the condition and control of existing capacitors and fuses, especially after a shutdown, may solve some power factor problems.
4. Installing the right size motor
Oversizing motors without proper power factor correction is a leading cause of low power factor. One of the most effective means of improving power factor is by installing correctly sized motors for the job. This will also reduce energy consumption and your total energy bill.
5. Power Quality Effects
Harmonics, a power quality phenomenon, may be generated by some electrical equipment, such as:
