Condition Monitoring System RFID LifeCheck
• Permanent condition monitoring of arresters with RFID LifeCheck
technology ensures a maximum degree of system protection and
availability
• The early detection system even detects pre-damaged arresters
and warns of imminent arrester failure
– Visual indication of faulty or pre-damaged arresters
– Compact dimensions and minimum wiring effort
– Monitoring of up to ten arresters (40 signal cores)
– Remote signalling contact
– Remote monitoring also via RS485 interface and PC software
(DRC MCM XT)
