Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto.

Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine 'The Australian Standard', which subscribing members receive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards.

Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

This standard was issued in draft form for comment as DR 84030.

PREFACE

This standard was prepared by the Association's Committee on Power Switchgear as a new edition of AS 1824, Part 2—1978.

It provides guidance in the application of AS 1824, Part 1.

This standard is based on IEC 71-2(1976) and IEC 71-3(1982)—Insulation Coordination, Part 2: Application Guide; and Part 3: Phase-to-phase insulation coordination, Principles, Rules and Application Guide. Acknowledgement is made of the assistance received from the above standards.

While this standard is technically similar to IEC 71-2 and IEC 71-3, it has been drafted so that it eliminates those portions of the IEC texts which it was felt did not contribute to the understanding or application of AS 1824, Part 1, or which would be more appropriately located in a textbook. Additionally, Appendix C of IEC 72-2 (Statistical Evaluation of the Protective Effect of Spark Gaps) is not included, as such an evaluation is not appropriate to a standard on insulation coordination.

Where this edition of this standard differs technically from AS 1824, Part 2—1978 and IEC 71-3 by amended or additional text, a rule is shown in the margin against the table, clause or part thereof affected and such deviations are summarized in the Annex.
