The presence of harmonic currents in the system also reduces the power factor. In some cases, due to improper wiring or electrical accidents, a condition known as 3-ϕ power imbalance occurs. This results in low power factor too. Power Factor Correction As discussed above, low power factor is mainly due to lagging currents drawn by inductive loads.

Steel mill tackles power quality and power factor problems

North Star Steel confronted low power factor (PF) and harmonics problems prior to installing a new ladle furnace by conducting a computerized analytical study using harmonic and power factor software. This study included field measurements of harmonics and PF on various feeders in the system. The Beaumont, Tex. company determined the characteristics of existing equipment and conductors.

The power factor values for the most common equipment and

A high power factor allows efficient use of energy, while a low power factor indicates poor utilization of electrical power. Each equipment or load has its own power factor and depends on the resistive or inductive load, some typical or common values for buildings, appliances and motors are shown below.

(PDF) Electrical Engineering Interview Questions

• Low lagging power factor causes a large voltage drop, hence extra regulation equipment is required to keep voltage drop within prescribed limits. • Greater conductor size: To transmit or distribute a fixed amount of power at fixed voltage, the conductors will have to carry more current at low power factor. This requires a large conductor
