When operated in accordance with their specifications, their service life can span as much as 30 years without any maintenance. Nevertheless, overloads may sometimes occur that can cause arrester failure and even endanger the safety of the network. Monitors assist in the early detection of relevant changes and support security of supply on a whole new level. Siemens offers a complete line of monitoring devices with a variety of innovative functionalities that can be perfectly matched to the customer’s requirements, ensuring that impending faults will be detected as early as possible and before the security of supply is compromised. 110 Based on solid experience Siemens has over 85 years of experience with surge arresters – a solid foundation on which to build a comprehensive range of monitors that are precisely tailored to today’s surge arrester technology. Siemens’ line of surge arrester monitors ranges from simple counters and condition indicators to periodic analytic condition monitoring and a future live condition monitoring system. All monitors provide the requisite information on surge arrester responses and the arrester’s condition – perfectly matched to the respective voltage level, network situation, and customer requirements.
