Reduce arc flash hazards
in bus ducts through thermal monitoring
Thermal avalanche risk in busway runs is a serious concern for electric utilities, data centers, industrial sites, as it can lead to arc flashes, which can cause severe injuries or even death. Arc flashes are caused by a sudden release of energy from an electrical arc, which can occur when there is a failure in the insulation or other components of the busway run.

One of the main causes of thermal avalanche risk in busway runs is the build-up of heat at joints. Joints are the points where different sections of the busway run connect, and they are often the weakest point in the system. As heat builds up at these joints, it can cause the insulation to degrade, which can lead to an arc flash.

To mitigate this risk, daisy chained magnetic temperature sensors can be used to monitor the temperature at joints 24x7. These sensors are magnetic, which means they can be easily mounted on the outside of the busway run. This allows for easy installation and maintenance, as well as the ability to monitor multiple joints at the same time.

The benefit of using magnetic temperature sensors is that they are non-invasive, meaning they do not require any modifications to the busway run itself. This means that they can be installed and removed quickly, without any damage to the busway run. Additionally, they are designed to be highly accurate, which means they can detect even small changes in temperature, making them ideal for monitoring joints.

Another benefit of using magnetic temperature sensors is that they can be easily integrated into existing monitoring systems. This allows utilities to keep track of the temperature of the busway run in real-time, and to take action if a potential thermal avalanche risk is detected.

In conclusion, thermal avalanche risk in busway runs is a serious concern for electric utilities. However, by using daisy chained magnetic temperature sensors to monitor the temperature at joints 24x7, utilities can mitigate this risk and prevent arc flashes from occurring. These sensors are non-invasive, easy to install and maintain, and highly accurate, making them an ideal solution for monitoring busway runs.
