Every IEEE Standard is subjected to review at least every ve years for revision or reafrmation. When a document is more than ve yea

Suggestions for changes in docu- ments should be in the form of a proposed change of text, together with appropriate supporting comments.

When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appro- priate responses. Since IEEE Standards represent a consensus of all concerned inter- ests, it is important to ensure
12、that any interpretation has also received the concurrence of a balance of interests.

16、ransformer Impulse Tests.) Early in 1955, a working group was appointed by the Dielectric Tests Subcommittee of the AIEE Transform- ers Committee to prepare an Impulse Test Guide for oil-immersed transformers. Members of the working group agreed to draft a portion of the guide in which they had a pa
17、rticular interest. The content of the 1986 guide was the consolidation and editing of these writings by the working group members. The power transformer standards of ANSI, IEEE, and NEMA, plus the purchasers specications, determine the specic requirements for impulse tests. This guide will not chang
18、e the standards in any way, but adds background information that will aid in the interpretation and application of these standards. These stan- dards now provide for some alternate ways of conducting some tests or parts of tests. These alternates have been developed by different testing laboratories
19、 with consideration for their individual problems of trans- former design, test facilities, etc. It is the object of this guide to discuss these differences and to show how effective failure detection can be achieved with the testing techniques employed. Although the guide is writ- ten primarily for
20、 power transformers, it is applicable generally to distribution and instrument transformers. The guide assumes the reader has an educational or practical background equivalent to that of a graduate electrical engineer with some knowledge of transformers. In late 1975, a Task Force was established wi
21、thin the Working Group, for Revision of Dielectric Tests, to review the original guide. It was their purpose to review the existing guide and revise areas where up-to-date oscillograms and procedures could be obtained. In February 1986, a Task Force was established within the Working Group, Revision
22、 of Dielectric Tests, to revise the 1986 Guide as follows: a)Addition of subclause 2.4: Lightning impulse testing of low impedance winding b)Addition of clause 3: Switching impulse testing c)Addition of clause 4: Digital transient recorder d)Other revisions included: 1)Addition of subclause 1.1: Sco
23、pe 2)Rewording of subclause 1.2: Impulse testing techniques 3)Additions to subclause 2.5: Failure detection 4)Additions to annex A: Bibliography 5)Change from the word oscillograph to oscilloscope in this guide where applicable.
