A fault current limiter for connection to a three phase AC supply comprises a first inductor 1 for connection to a first phase of the AC supply; a second inductor 2 for connection to a second phase of the AC supply and a third inductor 3 for connection to a third phase of the AC supply. Each of the first, second and third inductors comprises a coil, and each of the coils of the first, second and third inductors is such that the self-reactance of each of the first, second and third inductors are substantially equal to a first reactance value. Furthermore, the coils of each of the first, second and third inductors are arranged such that the mutual reactance between each pair of inductors is substantially equal to a second reactance value, and the second reactance value is substantially equal to the first reactance value. |
