Capacitor Changing Control At Optimal Control Operation - Mitsubishi Electric VAR-6A User Manual

4.8 Capacitor Changing Control at Optimal Control Operation

■
Optimal control is suitable for circuits with sharp load fluctuation. However
decreases gradually when multiple capacitors are closed
,
capacity and the capacitor with the largest capacity will remain last.
■
In the area where light load disconnection is not made
the capacity. Thus this last capacitor will not be cut off.
■
When the power factor leads out further than
control takes place where large capacity capacitor opens and small capacity capacitor closes.
Setting value of Target Power Factor is not 100 %.
