Dynamic PowerVar LV Filter

Power Survey’s Dynamic PowerVar LV thyristor-switched capacitor banks are used for ultra-rapid transient-free power factor compensation due to fast varying or large low voltage connected loads, giving additional benefits of transient-free compensation and voltage dip minimization.

With the Dynamic PowerVar LV technology, large capacitor steps can be connected to the network very fast. By using a step-up transformer, this solution can be also used for capacitive compensation in medium voltage installations.
