Hi Ian, I've had two surge generators made by another popular company fail recently. However, I always assume the decoupling network is . . . decoupling adequately, and never used an external EMI filter.
Does your surge generator have separate inputs for basic generator operation and EUT voltage? If so, which input is the filter on? Pat Lawler EMC Engineer SL Power Electronics Corp.
