Pfisterer High Voltage Surge Arresters up to 42kV

Pfisterer Connex surge arresters protect switchgear and transformers equipped with plug-in type high voltage bushings, 6.6kV up to 42kV.

Pfisterer Connex surge arresters are used to protect metal-enclosed switchgear fitted with cable terminations in accordance with EN 50180/EN 50181.

The high voltage surge arresters are connected to the switchgear transformer and prevent the entry of excessively high surges.
 
Surge arresters are particularly effective in limiting surges caused by reflected travelling waves and switching overvoltages.
