The text of this amendment is based on the following documents: Enquiry draft Report on voting 77A/669/CDV 77A/685/RVCFull information on the voting for the approval of this amendment can be found in the report on voting indicated in the above table. The committee has decided that the conte
29、nts of this amendment and the base publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edit

31、ces Replace the existing text of the first paragraph by the following new text: The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (incl
32、uding any amendments) applies. Convert dated references into undated references. 5 Test levels Replace the entire text after Table 1 with the following new text: The repetition period T and the duration t of the voltage fluctuations are specified as T = 5 s and t = 2 s (see Figure 1d). The changes f
33、rom the initial voltage to the test voltage, or from the test voltage back to the initial voltage are achieved through five successive voltage steps in five consecutive cycles of Amendment 2:2010 to CAN/CSA-CEI/IEC 61000-4-14-0161000-4-14 Amend. 2 IEC:2009 3 the mains supply, see Figure 1d. Each vol
34、tage step is of U/5 and occurs over /2 radians of the period of the nominal frequency, fn, (e.g. 5 ms for 50 Hz) see Figure 1b and Figure 1c. For falling voltage changes, the voltage step begins at phase angle = 270 and finishes at = 360, see Figure 1b. For rising voltage changes, the voltage step b
35、egins at phase angle = 180 and finishes at = 270, see Figure 1c. x is an open test level. This value may be defined by the product standard in order to cover situations other than the normal operating conditions of the network. All of the levels can be proposed by the product committee, but for equi
36、pment for use in public supply systems, the values shall not be lower than those specified for class 2. NOTE The upper and lower voltage operation limits defined by the product manufacturer should not be exceeded. 6.2 Characteristics and performance of the test generator Replace the existing Table 2
37、 by the following new Table: Table 2 Characteristics of the test generator Output voltage capability Un 15 % Voltage accuracy 1 % Zero crossing accuracy 250 s at zero voltage crossover Output current capability The generator shall be able to supply enough current according to the type of EUT in the
38、test voltage range. Overshoot/undershoot of the actual voltage Less than 5 % of the change in voltage Voltage rise (and fall) time during switching Under 1 ms Maximum interphase error (three-phase power supply) 2,5 Frequency accuracy 2,5 % of fn(50 Hz or 60 Hz) NOTE The generator with a power amplif
39、ier specified in IEC 61000-4-11 is suitable for this test. An over-voltage capability of Un+ 15 % is necessary. 6.3 Verification of the test generator Replace the second paragraph by the following new paragraphs: The test generator shall be verified that it complies with the characteristics and spec
40、ifications listed in Table 2. Performance of the test generator shall be verified with a resistive load drawing an r.m.s. current of no more than the output capability of the generator. For example, a 230 V/16 A generator shall be verified with a 14,3 load. In addition, the generators output current
41、 capability shall be verified as being able to provide a crest factor of at least 3 when Unis applied to a single phase load drawing an r.m.s. current of no more than the output capability of the generator. Each output phase of the generator shall be verified in turn. An example of a suitable 230 V/
