Damages caused by the unbalance of harmonic voltage in a low-voltage distribution system are discussed, the application principle of the symmetrical component method based on harmonics is analyzed; taking into account the regulations on voltage unbalance factor specified in national standard, the definition of the comprehensive unbalance factor of negative-sequence voltage and that of zero-sequence voltage are studied; the correctness of the theoretical analysis is proved by experiments; and the necessity of considering the unbalance of the harmonic voltage under nonlinear load is revealed through analysis.
