3. Interior protection system
3.1 Potential differences and priming
The first and most frequent cause of overvoltage is a lightning strike on, or near, an overhead line; the lightning current generates a local voltage pulse in the conductors of this line, which then propagates to the building. The closer the impact, the higher the amplitude of this pulse at the point where the line enters the building. The amplitudes of these surges are generally of the order of several thousand volts for low-voltage lines (220/380...
