A monitoring apparatus (30) for a superconducting cable comprises magnetic field probes (60) interspersed with conductors (50) that are part of, or connected to, the superconducting cable. A magnetic field sensor (62) is magnetically coupled to each probe (60) and is configured to produce an output signal depending on the sensed magnetic field. The output signals are analysed to determine the condition of the superconducting cable.
