Medium-voltage arrester for protecting transformers, switchgear installations and transmission lines against atmospheric and switching overvoltages according to IEC / EN 60099-4
For protecting d.c. systems and rectifier stations against surges. The arresters are especially suited for installation in rolling stock, trolley buses and overhead lines.
For electrical isolation of overloaded arresters. Disconnectors are series-connected with the medium-voltage arresters in its earth connection.
For recoding discharge processes of DEHNmid surge arresters and life cycle monitoring of DEHNmid surge arresters by measuring the leakage current via the IZM 100 impulse counter.
