Abstract
Embodiments of the disclosure include a fault current limiter having a first current splitting device including a primary winding and secondary winding wound around a first core, and a second current splitting device including a primary winding and a secondary winding wound around a second core. The fault current limiter may further include a fault current limiter module (e.g., a switching module) electrically connected in series between the secondary winding of the first current splitting device and the secondary winding of the second current splitting device. The fault current limiter may further include a second fault current limiter module electrically connected in series with the secondary winding of the second current splitting device. By splitting the fault current limiter into parts with fault current limiter modules interspersed between the windings, the fault current limiter may be to be built with less insulation between the windings.
