Transformer, system and method to control harmonic distortion

摘要: Harmonic distortion in a multiple phase power system is controlled by enabling different relationships to be set, and changed, the field, between devices being energized source providing energization. This has particular application, for example, canceling harmonics caused six-pulse variable frequency drives used controlling connected three-phase induction motors that operate electric submersible pumps. A transformer achieve this two winding groups, each with sets of contacts at relationships.
