Cable overheating

[Web app and mobile app]

Cable overheating detection provides an early warning system for the detection of overheating cables in low-voltage (LV) equipment, such as switchboards or panelboards. Overheating cables can cause equipment damage and fires.

PowerLogic™ HeatTag™ wireless sensors that are installed in the equipment can detect gases and particles that are released when cables are overheating. When the gas and particle concentration reaches a certain limit, the HeatTag sensors generate alarms that are displayed in Energy Hub.

warning

HAZARD OF FIRE

● Do not use Energy Hub as a safety system for your facility.
● Do not rely solely on software messages and reports to determine the correct operation of your building systems.
● Do not base your maintenance or service actions solely on information provided by the software.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

 

HeatTag alarms

Asset monitoring alarms

HeatTag devices generate a Thermal / temperature alarm when detecting cable overheating conditions. The priority of this alarm increases as the gas and particle concentration increases:

  • Low priority Thermal / temperature alarm (cables are beginning to overheat and maintenance actions should be planned).
  • Medium priority Thermal / temperature alarm (cables are overheating; timely action is required).
  • High priority Thermal / temperature alarm (cables are overheating fast; immediate action is required).

Diagnostics alarms

HeatTag devices generate two types of diagnostics alarms:

  • High priority Device replacement alarm (HeatTag sensor is out of service).
  • High priority Fan error alarm (HeatTag fan needs cleaning).
Energy Hub notifications

Energy Hub sends three types of notifications:

  • Notification when a HeatTag alarm goes active or inactive.
  • (*) Notification if HeatTag alarms have been active for more than two weeks. This notification is sent every two weeks until the alarms are no longer active.
  • (*) Notification if no alarms have been generated by HeatTag devices for a site in the previous three months.

(*) These notifications are not controlled by the notification settings in Energy Hub and cannot be disabled.

 

Overheating of cables can take days, weeks, or months until enough gas and particles are produced to trigger an alarm. However, continuous monitoring is important, which means you need a reliable communication network that connects the HeatTag sensors to the communication gateway and the gateway to Energy Hub.

NOTES:
  • Device-based communication loss alarms have a Low alarm priority in Energy Hub. Do not ignore these alarms for devices that are related to cable overheating detection monitoring.
  • You do not receive HeatTag alarms and notifications during a communication interruption between the HeatTag sensors, communication gateways, Energy Hub, and your email or mobile device.

Energy Hub includes a gateway communication loss software alarm that monitors the communication link between Energy Hub and the communication gateways. This alarm can notify you of communication issues. See software-based alarms to review the details of this alarm and to understand its behavior and limitations.

For detailed information on PowerLogic HeatTag sensors, see the HeatTag user guide (download page) and other product information available on the Schneider Electric website.

For information on the technology used by HeatTag sensors for detecting cable overheating, see [white paper]: New gas and particle sensing technology detects cables overheating in LV equipment (download page).

HeatTag devices generate device-based alarms for cable overheating detection. For details, see cable overheating detection details.

There are no software-based alarm types for cable overheating detection.

To learn more about alarming in Energy Hub, see Alarming.
For details on software-based alarms, see Software-based alarms.

Prerequisites

Verify that:

  • You have an active Energy Hub subscription that includes this feature. For information on subscriptions, see Energy Hub subscriptions.
  • HeatTag monitoring devices are installed in the relevant locations in your facility.
  • The monitoring devices are connected to communication gateways, for example Site Server or Panel Server, that are sending measurement data to Energy Hub over the internet.
  • The communication gateways have been added to your organization in Energy Hub.

Configuration

Cable overheating detection generates low, medium, and high priority asset monitoring alarms when detecting cable overheating conditions and high priority diagnostics alarms related to the operational condition of the HeatTag sensors. To receive alarm notifications for cable overheating detection alarms, verify that alarm notification is enabled for asset monitoring alarms with low, medium, and high priority.

  • No configuration is required for cable overheating detection.
  • To customize alarm notifications, edit the notification settings in Energy Hub.

For step-by-step instructions on how to edit notification settings, see To edit notification settings.

The monitoring and detection of cable overheating is done by the HeatTag sensors that are installed in your facility. When a HeatTag detects an overheating condition, it generates an alarm.

For step-by-step instructions on how to view alarm information, see To view alarm information.

[Web app]

You can create a report for cable overheating alarms by printing the data displays in the Asset view in Investigate, or by saving them as a PDF output. Printing or saving as PDF is not available for alarms displayed in Inbox. CSV export is not available for alarm displays. For step-by-step instructions on how to report on energy system data, see Reporting tasks.

[Mobile app]

There is no reporting for cable overheating detection in the mobile app.
