Differences between conventional and active (ESE) lightning rods

There are various types of external lightning protection technology, and questions commonly arise about the differences between them. To understand them properly, it is not enough simply to compare the equipment; it is also necessary to analyse how a

Different external lightning protection technologies for a single objective: Lightning protection is an essential element in the design of many infrastructures, particularly those where the safety of people and operational continuity are priorities. There are several external lightning protection technologies. Among the most widely used are conventional systems, based on air terminals or meshed cages (Faraday cages), as well as ESE systems (Early Streamer Emission lightning rods).

These two systems pursue a common objective: to intercept the atmospheric discharge and safely conduct the lightning current to earth. The choice between these two solutions must be made on the basis of technical criteria and the real needs of the installation. Depending on the characteristics of the infrastructure and its environment, it is possible to opt for a conventional system, an ESE system, or even a combination of the two in order to ensure effective lightning protection.
