    Surge Testing with Partial Discharge Surge Testing with Partial Discharge Partial discharge testing is an optional feature on the ADX. Contact Megger Baker Instruments support for information on adding the feature to your tester. NOTE: PD can occur from test leads to ground, or from lead to lead. Keeping test leads off of the floor and separated from each other can mitigate some issues that can affect PD test results.
