Abstract
The growth in the demand for electrical energy has led to the development and application of technologies that make its means of transport more efficient. Thus, one of these options is the implementation of transmission lines in HVDC. One of the parameters considered in the design of transmission lines is the distribution of their generated electric field. The following article presents the analysis and calculation of the electric field stress of a bipolar transmission line in HVDC, through the development and implementation of a methodology for teaching the calculation of the electric field stress in the corridor of a transmission line, replacing the ground plane with an image conductor identical to the conductor under study, but with opposite charge and positioning it at a distance below the ground plane. A case study of an 800 kV bipolar transmission line in HVDC is presented, the results obtained using the Field and Corona Effects (FACE) software were compared, the results are consistent with those obtained by the methodology, presenting a maximum percentage difference of 2%.
