Automatic Power Factor Control Panels are mainly used for the improvement of power factor. Power factor can be explained as ratio of active power to apparent power & it is a key factor in measuring electrical consumption.

Power factor is the ratio between the useful (true) power (KW) to the total (apparent) power (KVA) consumed by an item of AC. Electrical equipment or a complete electrical installation. It is a measure of how efficiently electrical power is converted into useful work output.
