摘要: A fault current limiter is provided that comprises a magnetically saturable core. The first core includes a first leg, a second leg, with a first AC coil wound on the second leg, a third leg, with a second AC coil wound around the third leg, the first and second AC coils being wound in series and connected to a first phase AC source, and a fourth leg. The first magnetic biasing unit is arranged to produce a first closed magnetic circuit in the first leg and the second leg that has a first flux direction, and the second coil is arranged to produce a second closed magnetic circuit in the fourth leg and the third leg that has a second flux direction, wherein the first flux direction opposes the second flux direction. The first and second AC coils are arranged to produce a first closed AC magnetic circuit in the second and third legs in an AC flux direction that alternates with each AC half-cycle.

摘要: A fault current limiter is provided for connection to a three phase AC supply. The fault current limiter comprises a first inductor for connection to a first phase of the AC supply; a second inductor for connection to a second phase of the AC supply; a third inductor 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.
