The selection of low voltage surge arrester systems<\/strong> and their specifications create debates, and systems are put under protection with wrong products within the scope of a huge chaos and competition anxiety. As a result, systems are damaged due to sudden overvoltage and lightning impulses. As Y\u0131lkomer, we put systems under protection by combining surge arrester selection and design, which we approach with correct survey and correct product recommendation as much as possible, with correct application. In this article, we will proceed step by step on LV Surge Arrester selection<\/strong> and try to enlighten you.<\/p>\n

AS YILKOMER, WE USE RAYCAP – ISKRA ZASCITE BRAND PRODUCTS AND PREFER SAFETEC TECHNOLOGY.<\/strong><\/p>\n

As Y\u0131lkomer, we carry out the country responsibility of the German company Raycap<\/strong>. Raycap is the company that holds the patent for STRIKESORB<\/strong> technology, which is integrated in series into systems we will launch in the upcoming period, and produces the most powerful surge arresters in this regard. With the company Iskra Zascite<\/strong> it has incorporated, it is also making a serious breakthrough in the panel type product group. It has 2400 different product types in the low voltage surge arrester group with its production facilities located in Germany, USA, Slovenia, and Greece. As Y\u0131lkomer, we protect every system at every voltage and current level by combining it with our engineering design with the 2400 different protection products we have.<\/p>\n

The concept of technology is extremely important primarily in low voltage surge arrester systems. As Y\u0131lkomer, we prefer SAFETEC<\/strong> technologies. Using products with only varistor technology causes the products to be easily damaged. At this point, our only goal is not to allow lightning impulses with safetec technology products where MOV+GDT, i.e., varistors are protected with gas discharge tubes<\/strong>. In addition, this technology, which protects the temperature effect in surge arresters with strong Thermal Control circuits, stands out as the best in its class.<\/p>\n

COMPLIANCE WITH STANDARDS IS EXTREMELY IMPORTANT IN LOW VOLTAGE SURGE ARRESTER SYSTEMS<\/strong><\/p>\n

Product and brand selection before design is extremely important. Compliance with international norms is of great importance in this regard. If we look at low voltage surge arrester standards<\/strong>;<\/p>\n

While IEC 62305 Ed.2 offers the most general risk analysis and design details on this subject, the IEC 62561 Standard gives us the details of the components used in the products. In terms of components, non-standard products cannot be expected to be successful against lightning impulses. The IEC 61643 Standard is a very important standard that determines the test criteria of Low Voltage Surge Arrester<\/strong> systems. Compliance with the IEC 61643 norm should be noted in the product tests received.<\/p>\n

IEC 61643-11<\/strong> ensures the determination of basic surge arrester electrical parameters. We indicate the important ones of these simple parameters below;<\/p>\n
