Abstract: The power distribution system is a power network system that is composed of a variety of power distribution equipment and power distribution facilities to transform voltage and directly distribute electrical energy to end users. As a part of the power system, the power distribution system directly faces end users, and its perfection directly affects the reliability and quality of power consumption of the majority of users, so it has an important position in the power system. Therefore, in order to avoid serious accidents such as equipment aging, equipment burnout, power supply interruption, fire and explosion of equipment due to high temperature, long-term temperature monitoring of each electrical node can avoid serious failures that may cause personal injury and economic loss to users.

This project is an application in a distribution room in Malaysia. It is used in a 33kV switchboard and needs to be equipped with wireless temperature measurement products to achieve safe temperature monitoring. The size of the copper bar is 10mm×130mm. Choose our ATE400 CT powered temperature sensor, and use ATC450 transceiver to connect to the display device. The RS485 communication data is transmitted to the customer platform for real-time monitoring, which can effectively prevent overheating failures, affecting the normal operation of the equipment, and avoiding potential safety hazards. For the sake of safety and economic benefits, it is recommended to conduct real-time temperature monitoring at each electrical node in the power distribution room.
