12、 1 of IEC 61869-5, prepared by IEC/TC 38, “Instrument transformers“, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61869-5:2011. The following dates are fixed: latest date by which the EN has to be implementedat national level by publication of an identicalnational
13、 standard or by endorsement (dop) 2012-05-17 latest date by which the national standards conflictingwith the EN have to be withdrawn (dow) 2014-08-17 This European Standard supersedes EN 60044-5:2004 regarding capacitor voltage transformers. EN 61869-5:2011 shall be read in conjunction with, and is
14、based on, EN 61869-1:2009, Instrument transformers - General Requirements. This Part 5 follows the structure of EN 61869-1 and supplements or modifies its corresponding clauses. When a particular clause/subclause of Part 1 is not mentioned in this Part 5, that clause/subclause applies as far as is r
15、easonable. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 shall be adapted accordingly. For additional clauses, subclauses, figures, tables, annexes or notes, the following numbering system is used: clauses, subclauses, tables, figures and notes th
