DETERMINATION OF THE POWER CABLES SYSTEM REDUCTION COEFFICIENT MATRIX

The work presents original theoretical bases of the mathematical model for determination power cables system reduction coefficient matrix. matter at hand is a new and completely general which can take into consideration an arbitrary number arrangement single-core cable arranged in treefoil formation. As fact, concerned matrix takes real (full) electromagnetic impact dominates pertaining cables, conditions occurrence one-pole short circuit. characterized by having elements dependant exclusively on geometrical properties very their positioning geophysical route, as well frequency currents flowing through cables. application deliberated here enables far more accurate estimation current distribution than would be possible applying separate factors present At same time, simple entirely general. presented theory developed also shown example with nominal voltage 110 kV.
