要約(英語): These days, no one can live without electricity and the power company must deliver the electricity both safely and continuously. In addition, power electronics technologies are adopted in many electric machines. With using the technologies, one can easily control the industrial electric machinery including the consumer electronics like televisions, is looking forward to saving energy, and can contribute to solving environmental problems. However, they have a point at issue that will generate the higher harmonics and give serious damages to the stationary devices, including the transformers and the capacitors for improvement of power factor, over the power delivery systems. Then, it is necessary to develop the system, which measures the power factor and harmonics and analyzes them. In this paper, the authors developed an analyzer for measuring power factor and harmonics in the power delivery system using a low cost single-board computer. Experiments have been carried out using the proposed system, and it is confirmed that the proposed analyzer has effectiveness.
