THE USE OF AG SURGE ARRESTERS IS MANDATORY IN FACTORIES AND INDUSTRIAL FACILITIES!

Lightning is a high-voltage electrical discharge that occurs between the cloud and the ground. In order for lightning to occur, the cloud and the ground must have different electrical charges and reach a certain potential difference. When the potential difference between the cloud and the ground increases and reaches a certain value, although the air is not conductive, a conductive channel is formed in the air and electrical discharge begins, that is, lightning occurs. In parallel with global warming in our country, the number and severity of lightning discharges closed 2018 with an increase of 300%. This incredible increase has highlighted the need to take the right precautions, especially in industrial and flammable explosive plants. The energy released in a lightning event is about 1010 joules, which can heat the temperature of the air column it passes through to 15,000 degrees Celsius in a millionth of a second. The burning and destructive effect of lightning is the result of this energy. This pulse, which can reach the power line of the facility, can burn all machines and systems in the order of nanoseconds and can cause the collapse of a very strategic point. The risk of fire is always of the 1st importance. Lightning strikes may fall directly on the plant, or it may proceed over high/low voltage lines or soil due to equipotential differences and cause damage to the facilities. It has the ability to affect an area within a radius of 2 kilometers from where the lightning strike fell. Due to the difference in impact resistance, it can proceed from the power line, data line, local communication network, CCTV line or Telecom line of the facility and damage the electrical devices and automation system in the facility. The use of UPS and generator systems does not protect the facility from lightning, on the contrary, these systems must be protected. In order to prevent serious damage, in addition to the physical protection created by lightning rods or passive capture tips, it is necessary to provide on-site protection with LV Surge Arrester products. AG Surge arrester products consist of 3 types. Raycap, which we are a partner of Yılkomer, has 2400 different surge arrester types and a reconnaissance study must be carried out for the correct protection of the facility. However, if we divide it into classes basically, Type 1 (Class B) is protected against lightning strikes; Type 2 (Class C) protection against sudden overvoltage shocks; Type 3 (Class D) are products used for the protection of sensitive devices. Product protection values, models show serious differences. Products should be selected according to Uc, Imax, Iimp values. With the advancement of technology, AG Surge Arrester products have also developed and products of type (Type 1 + 2 and Type 1 + 2 + 3) have emerged that provide all protection. The protection of factories and industrial facilities against impacts from the soil is ensured by step-by-step protection in the form of transformer AG exit points, protection of main distribution boards, protection of secondary distribution boards, protection of MCC and automation panels and protection of sensitive devices, respectively. Telecom lines, Ethernet lines, POE lines, Switches, Modems must be protected according to the results of the risk analysis. It is important to use the correct surge arrester rather than the use of surge arresters in the system. And even more so than the correct use of surge arresters, the correct product assembly is important. We recommend that you choose MOV+GDT hybrid technology (Safetec) products and assemble them with our expert staff after making discovery.

IS THE USE OF SURGE ARRESTERS MANDATORY IN TERMS OF STANDARDS AND REGULATIONS?

So far, we have tried to explain the use of surge arresters from a technical point of view. However, if you are an engineer in a facility and you are legally responsible for the facility, you should definitely take a look at the following items. In a possible negative situation, the issue is very important for both legal and insurance companies. INTERNAL INSTALLATION REGULATION ARTICLE 43 If there is an external lightning system in a facility within the scope of Article 43 of the Internal Facilities Regulation, the use of LV Surge Arrester is mandatory. REGULATION ON PROTECTION FROM LIGHTNING ARTICLE 25 Within the scope of Article 25 of the Lightning Protection Regulation, the use of LV Surge Arrester is mandatory in the facility. Translated as DKD -Impact protection mechanism.   WITHIN THE SCOPE OF OCCUPATIONAL SAFETY REGULATION, AG SURGE ARRESTER SHOULD BE USED. It is stated that the protection of the entire facility within the scope of the occupational safety regulation should be covered by the IEC 62305 Standard.   As a result, in order to avoid a negative situation both technically and legally, we recommend that you use LV Surge Arrester in your facility as soon as possible. https://www.yilkomer.com/fabrika-ve-endustriyel-tesislerde-ag-parafudr-kullanimi-zorunludur/
