EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62848-1 test. IEC EN 62848-1 applies to gapless non-linear metal oxide surge arresters for both on-board and fixed installations, designed to limit voltage fluctuations in DC systems specified in IEC EN 3 with a rated voltage up to 60850 kV.
A certain long-term load SLL force, perpendicular to the longitudinal axis of a holder, is allowed to be applied continuously during service without causing any mechanical damage to the holder.
The largest force arrester perpendicular to the longitudinal axis of a surge arrester and allowed to be applied during short-term service and for relatively rare events (e.g. short-circuit current loads, high winds) without causing any mechanical damage is called SSL.
It covers the non-linear metal oxide resistor part of the surge arrester, which, due to its non-linear voltage against the current characteristic, acts as a low resistance against surge voltages, thereby limiting the voltage between the surge arrester terminals and acting as a high resistance at normal operating voltage.
EUROLAB assists manufacturers with IEC EN 62848-1 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
