IEC 61000-4-27: Unbalance, immunity test
Standard Overview
IEC 61000-4-27 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. Establishes a reference for evaluating the immunity of electrical and electronic equipment when subjected to unbalanced power supply voltage. Applies to 50 Hz/60 Hz three-phase powered electrical and/or electronic equipment with rated line current up to 16 A per phase.
