Research of High-voltage Transmission Lines and Power Substation Electromagnetic Environment and Impact on Radio Signals

摘要

The analytical expressions of electromagnetic environment are derived for the high-voltage transmission lines and substation. And the scattering interference and shielding effect are analyzed. A test method is designed to measure the impact on wireless communication signals. The test results show that the transmission equipment can change the direction of wireless signals and influence the radio propagation attenuation.
