The research on the real time monitoring of the transmission lines is one of the directions for the power grid technologies. Seeing that the terminals of data acquisition system (DAS) of the real time monitoring of the transmission lines had to be located on the top of the tower, they were always in an unattended state, which brought out a protrusive problem of the power supply. This paper described a sort of power supply system featured as a hybrid of capacitors and solar batteries. The design of this power supply device must consider some important factors, such as how to take advantage of solar energy as full as possible and isolate from the high voltage electromagnetic interference. There are also many concrete details in the design of this supply device featured as a hybrid of super capacitors and solar batteries. The capacity of capacitors and solar batteries should also be deliberated to guarantee the maintainable supply at least one week even in the overcast and rainy days. This paper brought out some opinions on the solutions of the problems mentioned above. Related simulations were done to prove the effect of this power supply system of the monitoring system for transmission lines. The result showed that a hybrid energy storing system can play a better performance than single entire energy storing device.
