It considers immunity tests for electric and/or electronic equipment (apparatus and system) in its electro- magnetic 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 long- term effects (greater than a few minutes) is not considered in this standard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 61000.

Annex A describes the sources, effects and measurement of this disturbance. Unbalance is caused by either voltage amplitude or phase-shift variations. A formula for the calculation of the unbalance factor, based upon these parameters, is given in annex B. The purpose of the test is to investigate the influence of unbalance in a three-phase voltage system on equipment which may be sensitive to this disturbance, which could cause: overcurrents in a.c. rotating machines; generation of non-characteristic harmonics in electronic power converters; synchronization problems or control errors in the control part of electrical equipment (see annex A). © BSI 2009 BS EN 61000-4-27:2000+A1:2009 EN 61000-4-27:2000+A1:2009 6 5 Test levels The equipment under test (EUT) is set up at a steady mains voltage and is then subjected to unbalance sequences according to figure 2. Table 1 specifies the test levels which are derived as explained in annex C. The duration of the unbalance test, specified between 0,1 s to 60 s, can be taken as a general guide to study short-term effects.

Tests are respectively specified for equipment in relation to levels 2 and 3 in IEC 61000-2-4. The product committee may specify any test level; however, for equipment connected to public supply systems, it is recommended that the levels should not be lower than those defined for class 2. 6 Test equipment 6.1 Test generators The generator shall have provisions to prevent the emission of disturbances which, if injected in the power supply network, may influence the test results. The output voltage shall be adjusted to 1% of UN and the phase to 0,3°. © BSI 2009 BS EN 61000-4-27:2000+A1:2009 EN 61000-4-27:2000+A1:2009 7 Table 2 Characteristics of the generator CharacteristicPerformance specification Output voltage capability Output voltage accuracy2 % of UN.
