HeatTag Wireless Sensor for Early Detection of Overheating
Cables Presentation
HeatTag Description
Overview
The HeatTag is a wireless sensor for early detection of overheating wire
connections or overheating cables.
The HeatTag sensor helps prevent electrical distribution switchboards from being
damaged by means of analyzing gas and micro-particles in the air of the
switchboard and sending alerts before any smoke or insulator browning.
Features
The HeatTag sensor includes the following features:
• 3 levels of alert according to the criticality of the detected situation
• 11 levels of air quality index (0 to 10)
• Analysis of gas and micro-particles emitted by cable sheaths when
overheating
• Measurement of temperature and humidity in the switchboard
• Self-diagnostics
• Communication with Schneider Electric EcoStruxure™ panel servers or
gateways
• Integration in EcoStruxure™ solutions
Air Quality Index
The HeatTag sensor provides an air quality index, ranging from 0 (good) to 10,
and displays the air quality evolution trend in a table.
Air quality index from 0 to 9 is provided for information.
An alert is triggered when the air quality index is equal to 10.
Overheating Detection
The HeatTag sensor does not replace the fire protection devices of the building.
WARNING
HAZARD OF FIRE
• Do not use the HeatTag sensor as a safety device.
• Do not disable the other monitoring and safety devices of the equipment.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
When the HeatTag sensor has detected an abnormal overheating of the cable
sheath in the switchboard (quality index equal to 10), it triggers an alert.
Overheating can be caused by:
• one or several loose connections (too high contact resistance).
• an incorrectly sized cable compared to the rated current.
• overload not detected by the protective equipment.
Alerts are triggered with three criticality levels:
• Low level: a cable is slowly overheating in the installation, you must plan a
maintenance visit of the installation.
• Medium level: a cable is overheating in the installation, you must check
quickly the installation.
• High level: a cable is overheating in a very short time, you must check the
installation immediately.
