The temperature of the power cables has to be monitored constantly in real-time along its full length which can enable temperature and hotspots anomalies to be well located and properly investigated. The temperature information about cables offers users a great insight regarding the condition of underground distribution, Medium voltage, High-voltage and extra-high voltage along with subsea power cables. As more photovoltaic generation is coming, a resilient grid needs good monitoring that can help the engineers to decide how much of ampacity the cable can handle with safety.
The buried & subsea cables are an integral part of a transmission system. We can not go and see them and even tools that are available for assessing their condition constantly are very limited. We have to remember that alternative generation like renewable, distributed and many evolving patterns of energy consumption directly means that the power cable must be subjected to several fluctuating loads and other changes in the operation & environment. The effect of these changes can be seen in the temperature of the cables. A good cable temperature monitoring can offer valuable insight into your power cable behavior. You can make decisions about the deferring cable replacement and many more. The main thing is - you can be assured and be safe about gaining knowledge regarding your cable within much safe temperature limits.
