Abstract
A rate of change of current sensor includes two measurement coils, arranged such that the turns of the first and second measurement coils are interleaved. The rate of change of current sensor further comprises two return coils, arranged to progress in an opposite direction to the measurement coils. The coils form loops and progress substantially around a target measurement conductor. This ensures that the two measurement coils both receive the same electrostatic coupling from external conductors which are not the target of the measurement operation. Further, the two measurement coils are arranged such that the first coil and the second coil are, on average, the same distance to the current-carrying conductor of interest.
