Medium voltage automatic power factor correction/reactive power compensation systems are used everywhere that motors are still directly operated without power electronics, or other consumers with a low inductive cosφ place strain on the grid with reactive power in addition to their active-power requirements. Local supply of this reactive power by means of compensation systems relieves the burden on the supply grid and reduces losses.

ZDDQ SVG/STATCOM is a modular system from 6kv to35kv, supplies reactive power to distribution grids with high regulating dynamics, and carries out regulating tasks such as voltage regulation or influencing the flow of reactive power.
