Consequence of an Indirect Lightning Stroke

                                       Fig.J6(b) Lightning falls near an overhead line

•The lightning current generates overvoltages through electromagnetic induction in the distribution systemb.

•These overvoltages are propagated along the line to the electrical equipment inside the buildings

•The electrical installations inside the building are generally destroyed.

                                               Fig.J6 (c ) Lightning falls near a building.

•The lightning stroke generates the same types of overvoltage as those described opposite.
In addition, the lightning current rises back from the earth to the electrical installation, thus causing equipment .

•The electrical installations inside the building are generally destroyed
