System for temperature monitor in substation with ZigBee connectivity

Monitor substation equipment temperature is one of the most important factors for power systems to ensure safe transmission of electricity. Traditional methods for monitoring the substation temperature shows many disadvantages such as low accuracy, heavy workload, lack of real-time, etc. Therefore, a low cost, high accuracy and automatic method is needed for power system. This paper presents a temperature monitor system for substation with ZigBee connectivity. Node hardware, network protocol and software on PC were presented. Finally, the implementation performance shows the sensor nodes have an automatic, small size, low power consumption, and network stability.
