On the Dispersion of Lightning Current After a Direct Flash to a Building

Abstract

Simplifications often made when simulating the dispersion of lightning current can yield results that depart too much from the complex reality of a direct lightning flash to a building. The unpredictable occurrence of side-flashes increases even more the complexity. Such simulations, if taken at face value, might lead to unrealistic specifications for service-entrance surge-protective devices (SPDs). A real-world anecdote illustrates both the complexity and a case where an SPD with only modest ratings, compared with some present proposals, provided satisfactory protection on the power-port appliances of a residence.
