The International Electrotechnical Commission (IEC) has issued three new standards on electromagnetic compatibility-specifically IEC 61000-3-6 Ed. 2.0; IEC 61000-3-7 Ed. 2.0; and IEC 61000-3-13 Ed. 1.0. All deal with the assessment of emission limits. The first 6100-3-6 is a technical report, informative in nature that provides guidance on principles that can be used as the basis for determining the requirements for the connection of distorting installations to MV, HV, or EHV public power systems. For the purpose of the report, a distorting installation means an installation (which may be a load or a generator) that produces harmonics and/or inter-harmonics. The second IEC 61000-3-7 provides guidance on determining requirements for the connection of fluctuating installations to MV, HV, or EHV public power systems. A fluctuating installation is one (a load or a generator) that produces voltage flicker and/or rapid voltage changes. The third IEC 61000-3-13 provides guidance for the connection of an unbalanced, three-phase installation (load or generator) that produces voltage unbalance in the system.
