16、f EN 61869-1 and supplements or modifies its corresponding clauses. When a particular clause/subclause of Part 1 is not mentioned in this Part 3, that clause/subclause applies as far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1
17、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 that are numbered starting from 301 are additional to those in Part 1; additional annexes are lettered 3A, 3B, e

47、formers 1 Scope This part of IEC 61869 applies to new inductive voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. NOTE 301 Requirements specific to three-phase voltage transformers are not included in this standa
48、rd but, so far as they are relevant, the requirements in clauses 4 to 10 apply to these transformers and a few references to them are included in those clauses (e.g. see 3.1.303, 5.301.1, 5.301.2, 5.5.301, 6.13.301.1 and Table 304). All the transformers shall be suitable for measuring purposes, but, in addition, certain types may be suitable for protection purposes. Transformers for the dual purpose of measurement and protection shall comply with all clauses of this standard. 2 Normative references Clause 2
