Continuous Thermal Monitoring Option

Power-Zone 4 Low Voltage Switchgear is available with an optional continuous thermal monitoring solution to provide 24/7 temperature values for critical connections in the entire lineup. Continuous thermal monitoring can be used to monitor trends over time for identifying faulty connections. This option is based on digital technology, providing new ways to monitor and alert facility management and maintenance people on a continuous basis and between inspections. The Continuous Thermal Monitoring seamlessly integrates innovative wireless temperature sensor data with EcoStruxure™ Power Monitoring Expert (PME) to provide facility operations and maintenance teams insights into equipment’s thermal and humidity data. Live data, alarms, events, trends and notifications can be provided by the PME software. Digital services via EcoStruxure Asset Advisor can also be provided from secure Cloud-hosted analytics of the temperature data where advanced analytics can help expert service engineers identify patterns and abnormalities to predict when potential electrical fire risks may arise.

Sensor installation locations in PZ4 and QED-6 switchgear include the following (see diagram below):

Incoming phase connections of main breaker(s).
Outgoing phase connections of feeder breakers.

Connect up to 100 sensors per EcoStruxure Panel Server wireless data concentrator to monitor field connections. Up to five concentrators can be connected to the substation monitoring device to calculate temperature thresholds and to integrate with an HMI mounted on the door fo the switchgear. Option includes three door-mounted indicating lights for healthy, pre-alarm and alarm.

NOTE: Splice bars and joints are securely torqued with conical washers and are considered maintenance free. Since they are lower risk these points are not monitored in the standard monitoring solution.
