The main objective of the electrical installation protection system is to limit overvoltages to values that are acceptable for the equipment.
The electrical installation protection system consists of:
=one or more SPDs depending on the building configuration;
=the equipotential bonding: metallic mesh of exposed conductive parts.
Implementation
The procedure to protect the electrical and electronic systems of a building is as follows.
Search for information
=Identify all sensitive loads and their location in the building.
=Identify the electrical and electronic systems and their respective points of entry into the building.
=Check whether a lightning protection system is present on the building or in the vicinity.
=Become acquainted with the regulations applicable to the building’s location.
=Assess the risk of lightning strike according to the geographic location, type of power supply, lightning strike density, etc.
Solution implementation
=Install bonding conductors on frames by a mesh.
=Install a SPD in the LV incoming switchboard.
=Install an additional SPD in each subdistribution board located in the vicinity of sensitive equipment (see Fig.1).
In general, DC surge protection can provide significant benefits and advantages, especially in scenarios where the equipment is sensitive to voltage fluctuations or where there is a high risk of power surges. Benefits of DC Surge Protection Protection of Sensitive Equipment: Many electronic devices, especially those using DC power supplies, are sensitive to voltage fluctuations. Power surges […]
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) […]
Overvoltage may occur in electrical installations for various reasons. It may be caused by: 1. The distribution network as a result of lightning or any work carried out. 2. Lightning strikes (nearby or on buildings and PV installations, or on lightning conductors). 3. Variations in the electrical field due to lightning. Like all outdoor structures, […]
