Surge Arrester Leakage Current Testing: What the Resistive Component Actually Tells You
A surge arrester spends almost its entire life doing nothing. Between operations it sits there as an insulator with a very small current flowing through it. That current is the only window you have into its condition while it stays in service. The problem is that most of what you measure is capacitive current, not the resistive component… Read More: Surge Arrester Leakage Current Testing: What the Resistive Component Actually… »
