Bus duct thermal monitoring solution

Detect abnormal heat at bus duct joints before it leads to power loss, equipment damage, or safety risk. Continuous, joint-level monitoring enables earlier intervention and more reliable power distribution.

24/7 hotspot detection for reliable power distribution

Bus duct failures often originate at joints where conditions are difficult to monitor and develop over time. By delivering real-time thermal alerts at critical bus duct and busbar joints, the solutions allow operations to act before faults impacts system performance.

Maintenance becomes planned rather than reactive

Early visibility allows intervention during controlled conditions rather than in response to failure.

Teams reduce reliance on inspection cycles

Continuous data replaces the need to wait for the next thermographic survey

Interaction with energized bus duct systems is minimized

Monitoring removes the requirement for unnecessary manual inspection of high-risk areas.

Faults are detected at the exact joint where they develop

Rather than relying on indirect or distributed sensing, temperature is monitored directly at connection points where bus ducts are most vulnerable and failures originate.

Bus duct thermal monitoring solution brochure

Bus duct systems are critical to maintaining stable and reliable power distribution across your facility. Failures at joint level can lead to unplanned outages, operational disruption, and costly repair work.

Continuous thermal monitoring provides direct visibility into these critical connection points, helping identify developing temperature rise before it escalates into a failure.

Why choose Eaton Exertherm CTM for bus duct thermal monitoring?

Our CTM solution is designed as an OEM-neutral approach to bus duct monitoring, providing continuous visibility across critical bus duct joints regardless of manufacturer. It focuses on monitoring the connection points where thermal faults are most likely to develop, but are often difficult to detect using conventional or indirect monitoring methods.

By providing real-time insight into temperature changes at these joints, it enables earlier identification of developing issues and improves visibility into fault progression between inspection intervals. Suitable for both retrofit and new-build bus duct systems, the solution integrates easily into existing electrical infrastructure while reducing the need for interaction with energised assets during maintenance activities, supporting safer and more controlled working practices.

Eaton Exertherm CTM bus duct monitoring solution vs fibre-based monitoring

This comparison highlights the differences in joint-level precision, deployment complexity, and lifecycle impact across bus duct monitoring approaches.

Attributes	Eaton Exertherm CTM bus duct monitoring solution	Fibre optic monitoring	Operational impact of bus duct monitoring approach
Fault location accuracy	Identifies the exact bus duct joint and location of the issue	Indicates temperature variation along a sensing path, requiring interpretation	Enables faster fault identification at specific bus duct joints, reducing time to locate and address failures
Installation approach	Modular and installed alongside the bus duct system	Installed only after full bus duct system installation is complete	Simplifies deployment and aligns monitoring with system build, reducing installation complexity in new or phased projects
Full commissioning and configuration	Simple setup using DIP switch configuration with minimal commissioning effort	Complex commissioning of sensing points, alarm zones, and system calibration required	Reduces commissioning time and complexity, enabling faster transition to operational monitoring of bus duct systems
Maintenance requirements	No ongoing maintenance or periodic verification required	Requires regular maintenance, cleaning, and periodic functional checks	Lowers ongoing maintenance burden and reduces lifecycle costs associated with monitoring bus duct systems
System repair and replacement	Only damaged sensing elements require replacement	Fibre length and splice limitations may require full system replacement	Minimizes disruption during fault repair and reduces cost associated with maintaining bus duct monitoring systems
System integration	Open integration with EPMS, BMS, and SCADA systems without proprietary software	Often dependent on proprietary tools and software platforms	Simplifies integration into existing electrical infrastructure and reduces dependency on proprietary monitoring platforms
