METHOD AND APPARATUS FOR CURRENT CORRECTION

摘要

The disclosure relates to a method, apparatus and computer readable medium for compensating for capacitive coupling effects (140) in an inductive current sensor. The method comprises receiving a current of an electrical signal measured at a current sensor at an instant in time. The method further comprises applying a capacitive coupling compensation coefficient to a voltage of the electrical signal measured at a voltage sensor at the instant in time to obtain a capacitive coupling compensation value. Furthermore, the method comprises adjusting the current of the electrical signal using the capacitive coupling compensation value to obtain a compensated current of the electrical signal.
