Research on transposition efficiency of screens of three-phase cable lines with consideration of mutual phase disposition
Methodology that allows estimating the values of currents on the cable core screens and choosing the method of connection and grounding of screens is considered. To achieve the objective it is necessary to develop a mathematical model and to perform corresponding numeric calculations for the design and verification of efficiency of screen transposition taking into account the mutual phase disposition.
