According to the system, through one or a plurality of coils, electromagnetic induction is used, or through two or more conductors which are separated by insulators, electric field function is used for obtaining energy from electromagnetic field around a high-voltage power transmission line. The obtained electric energy is supplied to all equipment arranged on high potential through an adapter, such as monitoring equipment and signal transmission equipment. All equipment does not require an external power supply and are powered independently. The signal which is output from the monitoring device is converted to an electronic signal. After passing through an electric-to-optical converter, the electronic signal is transmitted through an optical fiber. The optical fiber can extend to an optical fiber joint box which is nearest and is at ground potential. Through an insulator, the optical fiber with high potential is jointed with the optical fiber joint box with ground potential, and the signal is transmitted to a remote monitoring center through the optical fiber with the ground potential. The optical fiber with high potential can further extend to an area which is provided with a low-potential power supply and is covered by the network. Then through a wireless network transmitter arranged in high potential, the signal is transmitted to a ground signal relay station, and finally remote transmission of the signal is realized.
