Abstract We in this paper have presented a model to assess the self and mutual impedances of power cables. We have introduced relations and experimented them for accuracy and reliability. We have described the single core cables with metal sheets and the cross-bonding. We have tested the model and the impact of metal sheets are elaborated in the work....

Abstract To reduce the unknown numbers and calculation time the transmission lines, symmetry can be considered. This will help to reduce unknown number in the quasi-static analysis. We have shown how the symmetry can be included in the measurement of quasi-static links with the help of the FEM formulation....

Abstract We in this work have presented algorithm for measuring the saving in electrical costs for industries that used the photovoltaic battery model. We also presented the dimensions and specification of the proposed system. Inside the demand side management program we have sued photovoltaic batter system for saving energy. We have experimented the model with real data and diagram of demand... We in this work have presented algorithm for measuring the saving in electrical costs for industries that used the photovoltaic battery model. We also presented the dimensions and specification of the proposed system. Inside the demand side management program we have sued photovoltaic batter system for saving energy. We have experimented the model with real data and diagram of demand in the selected industries and the results are described. Read More Read Less
