LEM has introduced a digital signal processor for Rogowski coil outputs at PCIM in Nuremberg. Rogowski coils are handy for current measurement because they simply wrap around the conductor carrying that current. However, they produce an output voltage proportional to the derivative of the primary current they are sensing, and therefore need an electrical integrator to ...
