The principle of
power saving
Reduce the active power (kw) by decreasing the power loss (Iron loss and copper loss) through eliminating Harmonic and Unbalance
Staged tab adjustment can help control the output voltage, helpful decreasing the output of a facility, and reducing the active power (kw).
Reduce the inactive power (Kvar) in order to get a discount for the basic electric charges when the power factor is 0.9 or higher.
