A. Reduces current for a given output
B. Increases loss in line
C. Increases the cost of equipment
D. All of above
Answer: A. Reduces current for a given output
Explanation:
Improving the PF can maximize current-carrying capacity, improve voltage to equipment, reduce power losses, and lower electric bills.
The simplest way to improve power factor is to add PF correction capacitors to the electrical system. PF correction capacitors act as reactive current generators.
They help offset the non-working power used by inductive loads, thereby improving the power factor.
The interaction between PF capacitors and specialized equipment, such as variable speed drives, requires a well designed system.
A lower power factor causes a higher current flow for a given load. As the line current increases, the voltage drop in the conductor increases, resulting in a lower voltage at the equipment.
With an improved power factor, the voltage drop in the conductor is reduced, improving the voltage at the equipment.
