The system for protecting a building against the effects of lightning must include:
=protection of structures against direct lightning strokes;
=protection of electrical installations against direct and indirect lightning strokes.
The basic principle for protection of an installation against the risk of lightning strikes is to prevent the disturbing energy from reaching sensitive equipment. To achieve this, it is necessary to:
=capture the lightning current and channel it to earth via the most direct path (avoiding the vicinity of sensitive equipment);
=perform equipotential bonding of the installation;
This equipotential bonding is implemented by bonding conductors, supplemented by Surge Protection Devices (SPDs) or spark gaps (e.g., antenna mast spark gap).
=minimize induced and indirect effects by installing SPDs and/or filters.Two protection systems are used to eliminate or limit overvoltages: they are known as the building protection system (for the outside of buildings) and the electrical installation protection system (for the inside of buildings).

Following in the footsteps of the previous article, let’s look at some tips to prevent the damage to surge protective devices (SPDs). 1. Overvoltage Conditions As surge protective devices (SPDs) break is due to overvoltage conditions, choosing a suitable voltage for the surge protective devices (SPDs) is important. 2. Burn-in of Surge Protective Devices (SPDs) […]
Surge protective devices (SPDs) play a critical role in protecting sensitive electronic equipment from unexpected voltage changes, such as voltage surges and spikes. These sudden voltage spikes can cause significant damage to equipment, leading to costly downtime and repair. In this article, we will explore the different components of Surge protective devices (SPDs) and describe their […]
