Damages caused by sudden overvoltage and lightning impulses are increasing day by day as a result of the rapid development of semiconductor technology and the use of components with decreasing resistance due to increased speed in power electronics. On the other hand, serious damage occurs in facilities where it is believed that the external lightning protection system protects against all effects of lightning and electrical protection is ignored. We have conveyed the importance of cascaded protection in LV Surge Arrester<\/strong><\/a><\/span> products, which protect all our electrical systems and equipment against lightning impulses along with impulses caused by switching elements, switching impulses, sudden voltage surges, grid impulses, motors and choke coils, air conditioning control systems, and long conductors, in every article. To summarize the subject, Type 1 (Class B) products protect against lightning impulses and reduce the Up level below 1.2 kV, while Type 2 (Class C) products provide protection against secondary impulses and reduce the Up level<\/strong> to around 0.6 kV. However, in sensitive devices, automation systems, and weak current systems, Up withstand capability is much lower, and therefore we need Type 3 protection. Besides the current intensity of the lightning impulse, the Up protection value of the LV Surge Arrester is also extremely important. We would like to recommend Type 1+2+3 new generation LV Surge Arrester products for the cascaded protection of the energy line. Especially in local protection points such as housing projects, datacenters, and server rooms, Type 1+2+3 LV Surge Arresters, which dampen energy in 3 stages, reduce the Up level in 3 stages.<\/p>\n

\"It<\/a>

It is of great importance to comply with standards in lightning protection methods.<\/p><\/div>\n

Although the product cartridge is longer than classic Type 1+2 LV Surge Arresters<\/strong> <\/a><\/em><\/span>, the technology of products providing 3-stage protection mainly features Safetec technology. 3-stage protection provides great benefits especially in single-panel open systems such as camera energy panels<\/strong><\/em>, GSM towers, and Telecom panels. It is observed that Type 3<\/strong> protection products are not frequently included in projects in our country, and Type 1+2<\/strong><\/em> products are predominantly used.<\/p>\n

\"protec-surge-arrester\"<\/a><\/p>\n

However, we definitely need Type 3 protection in sensitive systems we will protect, for example, on the card of a rectifier. By using a 3-stage LV Surge Arrester, we offer a definitive solution against lightning, grid, and switching impulses. Products containing Safetec<\/strong><\/em>, i.e., gas tubes alongside varistors, which have test values in 10\/350ms and 8\/20ms curves, reduce the Up level to around 0.25 kV. Products providing 3-stage protection definitely have a T3 protection value on them. With T1 T2 T3<\/strong><\/em> protection values, products capable of activating in different impulse characteristics are designed. In general, products that activate in 25 nanoseconds should be connected parallel to the system and commissioned using a 16 mm2 cable cross-section. If the cable cross-section is insufficient and the ground line circulates inside the panel exceeding 50cm, we will have performed an incorrect application. We can energize 3-stage protection products from a fuse with a value of 100 A. The related product is extremely suitable for short-distance applications, for example, in the entrance panels of apartments, residences, and villas. We protect all home electronics against external impulses. For example, you can protect your LED television from lightning impulses in this way. However, the related product applies to the cascaded protection of the energy line. External Type 3 protection products should be used in telecom lines, camera data and coaxial lines, signal and communication lines. You can contact Y\u0131lkomer Lightning Protection Center for 3-stage LV Surge Arresters<\/strong><\/em> in our stocks.<\/p>\n","protected":false},"excerpt":{"rendered":"
