GPR

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.

The FCC has issued a formal waiver of its Part 15 rules, permitting the certification of an innovative ground penetrating radar (GPR) device.

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.

Industry Canada limits for handheld and indoor communication devices are more stringent in part than the FCC’s. Test methods and equipment labeling also differ somewhat between the FCC and IC rules.
