Tell me about power factor and how to keep always .80?

Question

Accepted Answer

Power factor is a measure of how efficiently electrical power is being used. To maintain a power factor of 0.80, various measures can be taken.

Power factor is the ratio of real power (kW) to apparent power (kVA).
To improve power factor, reactive power should be reduced.
Installing power factor correction capacitors can help improve power factor.
Regular maintenance of electrical equipment can prevent power factor degradation.
Balancing loads across phases can also help maintain a power factor of 0.80.

Accepted Answer

Power Factor is the ratio of working power to apparent power, or kW / kVA. For example, an operation runs at 100 kW (working power) and the apparent power meter records 125 kVA. Dividing 100 kW by 125 kVA yields a power factor of 80 percent, meaning only 80 percent of incoming power does useful work.
