Ultra-Low Power Wireless Communication System for Cable Joints' Temperature Detecting

To the power supply network, the cable junction is the weakest link of the power cable. Especially in recent years, the city distribution line has been rebuilt with buried cables that substitute high-voltage line. Several companies at home and abroad are engaging in the related development, research and manufacture with underground power cable temperature. Because the cable junctions are usually wildly distributed, placed far away and have no low voltage power source, we designed a new temperature detecting and state analysis system for power grids cable joint based on the wireless communication methods and dynamic power management technology accordingly.
