Abstract

Three Phase Induction Motors are widely used in the industrial world, therefore induction motors are expected to operate normally according to the desired work characteristics. But can not be denied the existence of interference that can cause damage to work induction motor system that one of them is harmonics. The purpose of writing this article is to explain the working characteristics of three phase induction motor which generates harmonics and in operation also contains harmonics. The method used in the study analyzed the working characteristics of three phase induction motor which in its operation contains harmonics. The harmonic form is analyzed by using Fourier series representation. The results obtained from this study indicate that under operating conditions containing harmonics, the stator magnetic field generates a rotating harmonic field that produces a forward and backward mmf mmf. Another effect of this harmonic, is the incidence of harmonic torque which coincides with the fundamental torque produces vibration and noise which has considerable effect on the operation of three phase induction motors.

Abstract

The need for energy use, especially electrical energy continues to increase from year to year. One of the sectors that consume the largest electrical energy is the household sector which consumes about 27% of the total energy consumption of all sectors. The main energy source in Indonesia at this time still comes from fossil energy, although the government has tried to develop various renewable energy sources for the future. Solar energy is one of the renewable energies that is quite potential for Indonesia considering the level of solar radiation in Indonesia is quite high throughout the year. The selection of subsidized housing as the object of research is due to the existence of clear regulations and the number which also continues to increase every year. Through the collection of physical data on the research location, such as analysis of shadows, roof structure, solar irradiation data, average electric power usage, the average solar energy requirement of the subsidized housing will be obtained. Furthermore, by calculating the economic value, it will be obtained how the description of the possibility of applying solar energy to subsidized housing will be obtained. If possible, the application of solar energy in subsidized housing can help government programs to use renewable energy and reduce the use of fossil energy
