LifeCheck® technology

LifeCheck®The unique RFID-based LifeCheck® technology allows fast and easy testing of arresters without removing the module from the system circuit. It permanently monitors the condition of the arrester and detects electrical and thermal load on all protection components.

The DEHNrecord test devices of our Yellow/Line product series contactlessly detect possible arrester pre-damage without interfering with the system circuit. The condition monitoring module permanently monitors the condition of the arrester, thus ensuring maximum availability.
