Condition Monitoring System with LifeCheck Sensor

Information

Installed DEHNrecord condition monitoring system
    Permanent condition monitoring of LifeCheck-equipped arresters ensures a maximum degree of system protection and availability The early detection system already 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)

Description

Condition monitoring
The DRC MCM XT and DRC SCM XT condition monitoring systems are compact DIN rail mounted devices designed for condition monitoring of up to 10 pre-programmed BXT / BXTU arresters with an integrated LifeCheck monitoring circuit.

Integrated into the protection modules, LifeCheck permanently monitors the 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 via non-contact RFID technology. Stationary installed, a single condition monitoring unit allows condition-based maintenance of 10 BXT / BXTU arresters.

The unit acts like an early warning system, generating a fault message already in case of imminent arrester overload. This fault message is indicated by an integrated three-coloured LED and transmitted via an integrated remote signalling contact. Failure of the monitoring unit, e.g. due to a voltage breakdown, is also indicated via the remote signalling contact.
The Show function integrated in the DRC MCM XT and DRC SCM XT system allows to detect pre-damaged arresters in the monitoring group.

The DRC SCM XT device is ideally suited for small-sized installations and allows to monitor up to 10 protection modules with integrated LifeCheck. In case of larger installations with more than 10 arresters, the DRC MCM XT device with integrated RS485 interface is used. The condition monitoring units are connected via the integrated RS485 interfaces to synchronise the monitoring cycles. Up to 15 DRC MCM systems can be connected to one another at the RS485 bus, allowing up to 150 BLITZDUCTOR modules or 300 pairs to be monitored simultaneously with minimum wiring effort.

The "Status Display and Service Console" PC software
is optionally available for the DRC MCM XT condition monitoring system. It indicates the status of the arresters and addresses 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 at www.dehn-international.com (Service section) or is available as CD for a nominal fee.
