LOW VOLTAGE SURGE ARRESTERS MUST BE USED CORRECTLY IN SOLAR INVESTMENTS

As a Lightning Protection Center, low voltage surge arresters must be designed correctly in energy investments. We recommend the use of agparaffuder systems in AC, DC and communication lines. Solar systems installed on open land and roofs may be exposed to sudden overvoltage impacts, especially lightning strikes, at any time. This is a disaster for solar investments that aim to provide sustainable energy production for many years. Because lightning and sudden overvoltage fluctuations can fall repeatedly to a point, and in any case, energy production will be disrupted, especially when the whole system is renewed. In order to prevent this situation, DC power lines, inverter communication inputs, open panels, rectifiers, camera and led systems protections must be used in the facility, especially at Combinerbox points within the scope of IEC 62305 Standards. It is of great importance that the DC surge arresters to be used are long-lasting and continuously active. Because a surgearrester that is disabled at the first blow requires continuous inspection, so surgearresters with safetec technology should be used in systems in parallel with semiconductor technology. The product characteristics used must be suitable for protection against both lightning and network impacts. In terms of cost, only the products tested on the 10/350ms curve of the ground neutral line and the other phases tested on the 8/20 ms curve also provide effective protection in our facility. In the selection of DC low voltage surge arrester systems, the continuous voltage of the plant, the grounding type, the risk analysis of the region where the product is used and lightning statistics are very important in product selection. For this reason, the right product should be used at the right point by calculating within the scope of the project data. DC SurgeArrester systems with RAYCAP SAFTEC and STRİKESORB Technology ensure that the products are activated in an infinite time even if they are hit. When we look at surge arrester technologies, the use of semiconductor elements is at the forefront. Although it varies between class types, the use of varistors and zener diodes is mainly used to direct the impact. However, as the severity of the incoming impact increases, the varistor technology becomes insufficient and the product is disabled as a result of damage to the varistor, especially in the ground neutral line. This situation requires constant control, product monitoring and prevents sustainable protection in the system. Products with varistor technology under IEC norms are obliged to provide protection a maximum of 5 times. However, a blow that comes above its capacity also goes down to a single time. In difficult to reach areas such as solar systems, GSM towers, varistor products create problems. However, it is also a fact that the fastest damping is provided by the varistor technology. In parallel with the development of technology, gas discharge tube and sparkgap technologies are used as alternatives to varisored products. Despite the strength weakness of the varistor, more durable damping occurs in these technologies, but unfortunately in these technologies, especially in secondary impacts, the speed of the varistor cannot be reached. Many investors are left between the dilemma of varistor or sparkgap. Varistor products are activated in 25 nanoseconds, but the product destroys itself, sparkgap products are activated in 100 nanoseconds, product strength increases, but a situation of concern occurs in the face of lightning speed The riddle of speed or strength has ended with 3-compartment Safetec technology products that are rapidly adapting to today's technology by Raycap engineers. Raycap surge arrester systems provide strength from the speed of the varistor in the same cartridge, with tubes containing damping gas systems and durability with sparkgap technology. Thus, especially in Type 1 + 2 class products, the product is never disabled and contains all technologies in the same cartridge. Thus, the speed-strength equation comes to life in raycap surgearrester systems. In particular, SAFETEC technology provides sustainable protection of solar systems, gsm towers, flammable and explosive plants, cement plants from overvoltage and lightning protection. Overvoltage and lightning strikes pose a great risk, especially in structures with an external lightning system. As a result of the right technology and the right product selection, the systems can become 100% protected, but even if the product is Safetec technology, it is extremely important to correctly configure the coordination between the products, to determine the UC values correctly, to pay attention to the maximum and nominal current values and to design the correct installation surge arrester system. Raycap STRİKESORB technology products provide high performance protection with a durability of 10 years.
