Standards for digital recorders for measurements in high-voltage impulse tests
The background to the first standards for digital recorders for high-voltage impulse measurements is reviewed briefly. The emphasis in the first issues is given and the import of the decisions made in these early documents presented. The changes in the latest revision of Institute of Electrical and Electronics Engineers (IEEE) Std. 1122-1998 are reviewed briefly and contrasted with the approach in the latest Committee Draft for Voting on the revision of International Electrotechnical Commission (IEC) Document 1083-1. The importance of the changes in these documents is discussed. New work in the field is summarized and recent developments in digital recorders are discussed. The present status of digital measurements is summarized and proposals for future improvements to the standards are put forward.
