IEC 61000-4-27:2000/AMD1:2009 Electromagnetic compatibility (EMC) - Part 4-27: Testing and measurement techniques - Unbalance, immunity test for equipment with input current not exceeding 16 A per phase; Amendment 1
This part of IEC 61000 is a basic EMC (electromagnetic compatibility) publication. It considers immunity tests for electric and/or electronic equipment (apparatus and system) in its electromagnetic environment. Only conducted phenomena are considered@ including immunity tests for equipment connected to public and industrial networks. The object of this standard is to establish a reference for evaluating the immunity of electrical and electronic equipment when subjected to unbalanced power supply voltage. This standard applies to 50 Hz/60 Hz three-phase powered electrical and/or electronic equipment with rated line current up to 16 A per phase.This standard does not apply to equipment with three-phase plus neutral connection if that equipment 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 Hz distribution networks. This standard does not include tests for the zero-sequence unbalance factor. The immunity test levels required for a specific electromagnetic environment together with performance criteria are indicated in the product@ product family or generic standards as applicable. This immunity test should be included in product@ product family or generic standards when equipment is likely to show reduced performance or function when exposed to a supply voltage with voltage unbalance. The verification of the reliability of electrical components (capacitors@ motors@ etc.) and longterm effects (greater than a few minutes) is not considered in this standard.?
