Abstract
In the field of Rogowski coils for the measurement of current within a conductor there is provided an electrical interface (30) for connection to a Rogowski coil (10) arranged around a primary conductor (16). The electrical interface (30) includes an input (32) that is configured to sample an input voltage signal (us(n)) from the Rogowski coil (10). The electrical interface (30) also has an integrator circuit (34) which includes an integrator module (36) that is configured to integrate the sampled input voltage signal (us(n)) to provide an output voltage signal (u INT (n)) from which can be derived a primary current (ip(n)) flowing through the primary conductor (16). The integrator module (36) employs a transfer function that includes an attenuation factor (A).
