35、trical testing FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standar

36、dization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation

37、 is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with th

38、e International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects

39、 since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical con

40、tent of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possi

41、ble in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformi

42、ty assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its director

43、s, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising ou

44、t of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn

45、to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60700-1 has been prepared by subcommittee 22F: Power electronics for electrical transm

46、ission and distribution systems, of IEC technical committee 22: Power electronic systems and equipment. This second edition cancels and replaces the first edition published in 1998, its Amendment 1:2003 and its Amendment 2: 2008. This edition constitutes a technical revision. This edition includes t

47、he following significant technical changes with respect to the previous edition. a) Definitions of terms “redundant thyristor levels”, “thyristor level”, “valve section” have been changed for clarification. b) The notes were added to test requirements of dielectric d.c. voltage tests for valve suppo

48、rt, MVU, valve, specifying that before repeating the test with opposite polarity, the tested BS EN 60700-1:2015 6 IEC 60700-1:2015 IEC 2015 object may be short-circuited and earthed for several hours. The same procedure may be followed at the end of the d.c. voltage test. c) Table 1 on thyristor lev

49、el faults permitted during type tests was supplemented. d) The alternative MVU dielectric test method was added. e) It was specified that production tests may include routine tests as well as sample tests. f) It was added into test requirements for periodic firing and extinction tests that a scaling factor for tests shall be applied when testing with valve sections. The text of this standard is based on the following documents: CDV Report on voting 22F/341/CDV 22F/351A/RVC Full information on the vo
