IEC 62305 – Protection Against Lightning, is the apex level document that informs the standards for lightning protection around the world. It is a design standard that comprises of four documents that provide the lightning protection designers with the rules and regulations they require to design an LPS.
How does lightning protection system work?
A lightning protection system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground for potential strikes. Lightning protection systems are used to prevent lightning strike damage to structures.

What is the 30 30 rule for lightning safety?
Don’t forget the 30-30 rule. After you see lightning, start counting to 30. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.
How many types of lightning arresters are there?
The types of lightning arresters are rod, sphere, horn, multi gap, electrolyte, and metal oxide. The types of surge arrestors are distribution, low-voltage, station, DC, neutral protection, fiber tube, signal, network, etc. This arrester can be used as a surge arrester.
What class is LPS?
Classes of LPS I, II, III and IV are defined as a set of construction rules based on the corresponding lightning protection level (LPL). Each set comprises level-dependent (e.g. radius of the rolling sphere, mesh size) and level-independent construction rules (e.g. cross-sections, materials).
