Description
IC impedances were developed within the Enedis MALTEN project. The compensating impedance is tuned automatically, with neutral current of 80–600 A or 80–1000 A. Neutral coils use a zigzag connection, are oil-filled and intended for outdoor installation. A homopolar generator of 40–80 kvar is rated for a fault current of 15–50 A. All equipment has natural ONAN cooling.
