Operation of a transmission system of FM radio facing the energy supply

The constant technological developments in radio since the discovery of the first experiments by Guglielmo Marconi, plus the contributions of the inventions of James Maxwell and Heinrich Hertz, made the radio became a vehicle of mass communication. With the success of radio and the evolution of electronics that began with the three-way transmission and later with the discovery of the transistor, a component that enabled the mobility of the radio receiver, the transmitting stations of FM stations and OM suffered great transformations of the standpoint of equipment size and power consumption. This provided an increasing use of nonlinear loads in all sectors, particularly in the transmission systems of networks. This paper presents measurements on a bus that feeds nonlinear loads in common facilities of a broadcasting station FM radio and analyzes the current harmonic distortion. It discusses whether the individual and total harmonic distortions are in accordance with Resolution 345 / 2008 of National Electric Energy Agency (ANEEL).
