This paper describes the design and implementation of an experimental electric power system to replace a gasoline system of a 30-feet unmanned autonomous blimp. The project was motivated by limitations and inefficiencies of the gasoline system. Autonomous flight requires extended duration flight and maneuvering capabilities that can be realized with an electric power system. In order to fully e...

Electric power is the mainstay of a nation’s economy and the lifeline of industrial production and social life. All parameters of an electric grid, especially harmonic parameters, are related to the quality of electricity generated, which guarantees safe operation of electric equipment. Therefore, this design combines a web-based electric grid parameter measurement system with a video-monitorin...

In the extremely low frequency range (3 to 300 Hz), the intensities of electric and magnetic fields increase with increasing voltage and current. If the intensities of electric and magnetic fields are high compared with standard exposure limits, they can have harmful effects on human health. In the vicinity of power lines and high voltage power stations, the intensities of these fields are usua...
