A Method of Power Loss Assessment in Low Voltage Cables for Industrial Electrical Grids
Current harmonics in industrial cable lines are accompanied by harmful phenomena that cause additional active power losses in cable cores. The phenomena are an increasing the insulation temperature and reduction cable lifetime. Failures are often noted in the cable electrical grids due to improper accounting for the impact of harmonics in the cable sizing. Therefore, the correct consideration of the active power loss in cables carrying distorted currents allows for the correct sizing its types and avoid potential problems in the power grid operation.
