Protection of Building and allied structure by lightning

Rajesh D Panchal

Abstract :

The lighting is a natural hazard which is discharged as static electricity. The important point by considering damage point of view is return stroke. The current discharged by the return stroke is about 2kA to 200kA. This current flashes to the ground from the negative charged cells in the thunder cloud. There is less chances of strokes from positive charge to the ground. The rising time of the negative charged flash is in the order of 10µs and that of decay time less than 100µs. The multi stroke may be 10 strokes together. The estimated potential of the charged flash is approximately. The cloud potential may be 100MV.
