DEAN Technology's distributed fiber optic bus duct temperature monitoring system has been deployed at Beijing Jinli Zhidi Center to provide real-time temperature monitoring for the facility's bus duct system.
By continuously monitoring temperature conditions along the busbars and at critical connection points, the system helps facility operators identify abnormal temperature rise and respond to potential overheating risks before they develop into more serious electrical safety problems.
In large commercial buildings, reliable electrical distribution is essential for maintaining safe and continuous operations.
Bus ducts and busbars carry large electrical loads throughout the power distribution system. Connections and plug-in points can be particularly important monitoring locations because abnormal temperature rise may indicate conditions that require inspection or maintenance.
Continuous temperature monitoring therefore gives facility operators greater visibility into the thermal condition of critical electrical distribution equipment.
The system deployed at Beijing Jinli Zhidi Center uses distributed fiber optic temperature sensing to continuously monitor temperature conditions along the bus duct system.
Unlike conventional temperature monitoring based only on individual measurement points, distributed fiber optic sensing uses optical fiber as a continuous sensing medium. This allows temperature conditions to be monitored across the installed sensing route rather than only at a limited number of discrete sensor locations.
For the Jinli Zhidi Center project, the system monitors temperature changes at busbar plug-in connections and other monitored locations. When an abnormal temperature condition is detected, the system generates an alarm so that operating personnel can investigate and take appropriate action.
Abnormal temperature rise in electrical distribution equipment can be an important indication of a developing problem.
Continuous bus duct temperature monitoring can help operators:
Identify abnormal temperature rise
Monitor critical busbar connection points
Detect potential overheating conditions earlier
Receive alarms when monitored temperatures become abnormal
Support preventive inspection and maintenance
Reduce the risk of overheating developing into a more serious electrical safety event
By identifying thermal abnormalities earlier, maintenance teams have more information available when deciding where inspection or corrective action may be required.
Fiber optic sensing is well suited to temperature monitoring applications in electrical infrastructure because the sensing medium is optical rather than a conventional electrical sensor installed at each measurement point.
Distributed temperature sensing can be applied to a range of power infrastructure where continuous thermal monitoring is valuable, including:
Bus ducts and busbars
Power cables and cable routes
Switchgear
Transformers and reactors
Other critical electrical distribution equipment

The deployment at Beijing Jinli Zhidi Center demonstrates how distributed fiber optic temperature monitoring can be used to improve visibility into the operating condition of bus duct systems in large commercial facilities.
Through continuous temperature monitoring and abnormal-temperature alarms, the system provides facility operators with an additional tool for identifying potential overheating risks and supporting preventive maintenance.
DEAN Technology provides distributed fiber optic temperature sensing and monitoring solutions for power systems and other critical infrastructure applications.
