Electropotential (voltage)


Electropotential difference (voltage) is the size of the voltage, and differences in the size of the voltage cause current to flow. Therefore the increase in electropotential cause when a lightning surge enters a ground generates electropotential difference, which can damage equipment. In terms of lightning countermeasures, it is necessary to inter-connect the grounds in order to achieve equal electropotential (equipotential bonding).
