  • Page 196 Appendix 9 Definitions Power Factor Power factor is the ratio of effective power to apparent power. The larger the ab- solute value of the power factor, the greater the proportion of effective power, (PF/DPF) which provides the power that is consumed, and the greater the efficiency. The maximum absolute value is 1.
