27.5KV 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.

3.3KV local reactive power compensation systems( APFC automatic power factor correction) 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.
