Production Description

M.V. Surge Arresters are used to protect transformers and other equipments in station and distribution systems against the damage
by atmospheric (especially lightning effects) and operational conditions.Metal oxides surge arresters without gaps are designed to
prevent probable damages in the case of typical surges in energy systems while it has no negative effect on energy systems in
normal operation voltage. This special feature of gapless arresters originating from non-linear characteristics of metal-oxide
varistors between voltage and current scales. The non-linear feature is much higher compared to SiC surge arresters.
