A Surge Arrester Type 2, also known as a Class II Surge Arrester, is a specific type of surge protection device designed to protect electrical systems and equipment from transient overvoltages or surges that result from switching operations and indirect lightning strikes. These surges are typically of lower energy than the direct lightning strikes handled by Type 1 Surge Arresters. Type 2 Surge Arresters are designed to handle surges with lower energy levels, which are common in electrical systems due to internal switching operations, inductive loads, or nearby lightning strikes that do not directly strike the building or power lines. They have a lower voltage protection level compared to Type 1 Surge Arresters. Type 2 Surge Arresters are typically installed at the sub-distribution level, where they provide secondary protection for electrical panels, distribution boards, and sensitive equipment within a building or facility. Overall, Surge Arrester Type 2 is an essential component of a comprehensive surge protection system, especially in areas where the risk of indirect lightning strikes and switching surges is prevalent.
