Cheatsheet for calculating lightning surge arrester ratings
The power grid is subjected to temporary over-voltages, described in detail in IEEE 142 – Grounding standard. This is not the same as a lightning strike or a switching surge. Its severity is much lower and, depending on the duration, does not warrant an arrester operation.
Harvesting lightning energy
Since the late 1980s, there have been several attempts to investigate the possibility of harvesting lightning energy. A single bolt of lightning carries a relatively large amount of energy (approximately 7 gigajoules or about the energy stored in 38 Imperial gallons or 172 litres of gasoline). However, this energy is concentrated in a small location and is passed during an extremely short period of time (microseconds ); therefore, extremely high electrical power is invol…
