Details
Condition Monitoring The DRC MCM XT condition monitoring system is a compact DIN rail mounted device for condition monitoring of up to 10 pre-programmed BXT/BXTU arresters with integrated LifeCheck monitoring circuit. Integrated in the SPD modules, LifeCheck permanently monitors the proper condition of the arrester and acts like an early warning system, detecting imminent electrical or thermal overload of the protection components. The LifeCheck status can be read out via contactless RFID technology. Stationary installed, the condition monitoring system allows condition-based maintenance of 10 BXT/BXTU. The unit acts like an early warning system, generating a fault message already in case of imminent arrester overload, that is indicated by means of the integrated three-coloured LED and transmitted via one of two integrated remote signalling contacts. Failure of the monitoring unit, e.g. due to a voltage breakdown, is also indicated via remote signalling contacts. The Show function integrated in the DRC MCM system allows to detect previously damaged arresters in the monitoring group. If several condition monitoring systems are used in a single switchgear cabinet, these systems are connected via their integrated RS485 interfaces to synchronise the monitoring cycles. Up to 15 DRC MCM systems can be interconnected at the RS485 bus, allowing up to 150 BLITZDUCTOR modules or 300 pairs to be monitored at the same time with minimum wiring effort. The "Status Display and Service Console" PC software is an optional user software for the DRC MCM XT condition monitoring system. It allows status indication and addressing of the LifeCheck-equipped BLITZDUCTOR modules. The software can be installed on a standard PC using an RS485/USB interface converter of type "USB-NANO 485" which is available as accessory. The software can be downloaded free of charge from www.dehn.de/download/ or is available as CD for a nominal fee. |
