適用范圍：This part of IEC 61000 is a basic EMC (electromagnetic compatibility) publication. It considersimmunity tests for electric and/or electronic equipment (apparatus and system) in its electromagneticenvironment. Only conducted phenomena are considered, including immunity testsfor equipment connected to public and industrial networks.The object of this standard is to establish a reference for evaluating the immunity of electricaland electronic equipment when subjected to unbalanced power supply voltage.This standard applies to 50 Hz/60 Hz three-phase powered electrical and/or electronicequipment with rated line current up to 16 A per phase.This standard does not apply to equipment with three-phase plus neutral connection if thatequipment operates as a group of single-phase loads connected between phase and neutral.This standard does not apply to electrical and/or electronic equipment connected to a.c. 400 Hzdistribution networks.This standard does not include tests for the zero-sequence unbalance factor.The immunity test levels required for a specific electromagnetic environment together withperformance criteria are indicated in the product, product family or generic standards asapplicable. This immunity test should be included in product, product family or genericstandards when equipment is likely to show reduced performance or function when exposed toa supply voltage with voltage unbalance.The verification of the reliability of electrical components (capacitors, motors, etc.) and longtermeffects (greater than a few minutes) is not considered in this standard.
