Current limiting reactors are needed to limit short-circuit currents to a level compatible with the capability of other system components. The product range includes load flow control, load balancing and bus-tie reactors. They can be installed up to the highest system voltages (765 kV). Coil Innovation supplies neutral grounding/earthing reactors that are connected between the star point of the transmission network and ground/earth in order to limit the line-to-earth fault current.
