The induced current on the cable in the IBDN caused by the lightning stroke to ground

The magnetic field produced by a lightning stroke may induce a strong current on power line and communication cables, and this induced current can propagate into an integrated building distribution network (IBDN) or a commercial building network and cause harmful effects. The paper proposes a model...

Description
Summary:The magnetic field produced by a lightning stroke may induce a strong current on power line and communication cables, and this induced current can propagate into an integrated building distribution network (IBDN) or a commercial building network and cause harmful effects. The paper proposes a model based on transmission line theory. The induced currents on both the cable sheath and the core are analyzed. The precise formulations for calculating these current are given.
