In this article, I have listed the possible damage that lightning strike could impart into structures. In addition to this, lightning could likewise disrupt services.
IEC 62305-1 provides a list of possible disruptions to services. In gas pipelines, lightning could lead to explosions. Proper lightning protection is necessary to prevent any possibility of disruptions or worst damages to public services.
| Type of service | Effects of lightning |
|---|---|
| Telecommunication line | Mechanical damage to the line, melting of screens and conductors, breakdown of insulation of cable and equipment leading to a primary failure with immediate loss of service Secondary failures on the optical fiber cables with damage to the cable but without loss of service |
| Power lines | Damages to insulators of low voltage overhead line, puncturing of insulation of cable line, breakdown of insulation of line equipment and of transformers, with consequential loss of service |
| Water pipes | Damages to electrical and electronic control equipment likely to cause loss of service |
| Gas pipes Fuel pipes |
Puncturing of non-metallic flange gaskets likely to cause fire and/or explosion. Damage to electrical and electronic control equipment likely to cause loss of service |
