Abstract We in this work have addressed the modelling of two-dimensional magnetic fields and analyse the three phase induction motors. During the calculation of the magnetic data, we look at the precision of the machines. We found that the magnetic field solution needs to be accurate for efficiency. We have used the set of programs for the generation of finite elements.... We in this work have addressed the modelling of two-dimensional magnetic fields and analyse the three phase induction motors. During the calculation of the magnetic data, we look at the precision of the machines. We found that the magnetic field solution needs to be accurate for efficiency. We have used the set of programs for the generation of finite elements. The air gap flux distribution of flux is the main determinant of the execution of the motor windings during the distribution of electromagnetic field. Read More Read Less

Abstract We studied the variations of the metal-oxide surges during many environments in this work. We studied the model of the influence of the lighting strokes that occur during the electric distribution lines. The distribution lines of the electrical equipment of the substation are examined during the process.... We studied the variations of the metal-oxide surges during many environments in this work.

Abstract The criteria used for the free space optics communication system during atmospheric turbulences are measured. These are derived from the closed form of expressions for standard performance measures. We observed the channel capacity used for carrying out the performance analysis over various FSO transmission scenarios. The M model represents the general turbulence it will reduce the other turbulence models received... The criteria used for the free space optics communication system during atmospheric turbulences are measured. These are derived from the closed form of expressions for standard performance measures. We observed the channel capacity used for carrying out the performance analysis over various FSO transmission scenarios. The M model represents the general turbulence it will reduce the other turbulence models received from the bit error rate. While capturing the expressions, the values given in the modulation formats and ergodic cc are also assessed like the number of large-scale cells of the scattering process. The mean power of the scatter components of the fading coupled with the line off-sight component is also studied. Read More Read Less
