Electrical Internal Installation Inspection
15 March 2016The Concept of Grounding and Equipotential Bonding in Solar Systems
18 March 2016Mosques and one of their most important structural elements, minarets, are systems with a high risk of lightning strikes due to their pointed and tall structures. Considering the human population in mosques, mosques are high-risk areas that must be protected against lightning and overvoltage. On the other hand, while mosques are protected especially with external lightning protection systems, they should be installed with attention to the architectural structure.
Use of External Lightning Protection in Mosques
External lightning protection systems are used to protect mosques against the physical effects of lightning. According to the IEC 62305 standard, the most suitable system structurally for mosques is the use of a lightning air terminal. The critical point to consider here is that the lightning down conductor must be insulated and selected in accordance with the architectural structure. Otherwise, there will be a risk of electric shock for people. Instead of lightning rods, it is important to prefer passive air terminals and use insulated systems. Selecting anticorrosive products will not damage the aesthetic appearance of mosques. Mosques are structures with a high risk coefficient where the rolling sphere method must be taken as a basis. Mosques must definitely be protected against the most important risk, which is fire.
Surge Arrester Usage
Electronic systems in mosques should also be protected with internal lightning protection surge arrester systems. In facilities with external lightning protection, the use of Class B surge arresters in main panels is mandatory. On the other hand, lightning impulses or possible internal overvoltages may damage sound and video systems. While using Class C surge arresters in sub-panels, sensitive electronic systems should be protected with Class D surge arresters. A lightning strike on the lightning rod or air terminal can damage all electrical systems in the mosque. Therefore, low voltage surge arresters should be used in energy panels, cameras, security systems, and sound systems.
