Failures Caused by Ground Potential Rise (GPR) at Interconnected Houses

Much has been written about failures due to ground potential rise (GPR), generally in connection with single houses with multiple grounds. But in cases where multiple houses are interconnected via a single piece of equipment, equipment failures could be caused by insulation issues due to GPR attributable to lightning.

Do Classical Calculations of Induction Due to Nearby Lightning Give Misleading Results?

Why the effects of nearby lightning might be over-estimated, or in some cases underestimated, and how to get more realistic estimates.

Lightning Induced Ground Potential Rise (GPR)

Select the most suitable waveforms for evaluating equipment resistibility to lightning damage when a GPR is either the suspected source of the damage, or its effects are to be tested for.
