Abstract: Reliable and stable power supply is a key to an effective operation of on-line monitoring equipment of a high voltage (HV) transmission system. This paper reviews power supply technologies commonly used for on-line monitoring terminal of transmission lines with a focus on energy collection and storage. Energy collection technologies include mainly the taking of electricity from the measured system, the taking of electricity from the outside of the measured system, and combining electricity using multiple ways. The energy storage technologies include electrochemical based battery technologies and supercapacitor based storage technologies. The advantages of these technologies and the problems that remain to be resolved are summarized. Based on the above, we discussed future development trends of power supply modes of on-line monitoring systems.

Key words: high voltage transmission system, energy harvesting technology, transmission line monitoring device
