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.

Effects of Lightning on ICT Circuits: Induction and GCR

Generally the effect of lightning on an information and technology (ICT) loop that we worry about most is damage. Let’s consider an ICT loop that is probably the most exposed to the effects of lightning – one that runs between structures.
