METHOD FOR MEASURING POWER LOSS OF ASYMMETRIC CURRENTS IN THREE-PHASE TRANSFORMERS AND FOUR-WIRE POWER LINES

摘要

FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering, in particular to determining power losses in power transmission systems. Method for measuring power loss of asymmetric currents in three-phase transformers and four-wire power lines comprises measuring at asymmetric load coefficients of reverse and zero sequence of currents in the three-phase transformer (four-wire line) and determining asymmetric currents power losses coefficient according to the measurement results.EFFECT: technical result is possibility to determine separate power loss of asymmetric currents in three-phase transformers and four-wire power transmission lines.1 cl, 1 tbl
