New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 100) which is identical with IEC 62689-100 : 2016 ‘Current and voltage sensors or detectors to be used for fault passage indication purposes — Part 100: Requirements and proposals for the IEC 61850 series data model extensions to support fault passage indicator applications’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on recommendation of the Instrument Transformers Sectional Committee and approval of the Electrotechnical Division Council.

This Indian Standard is published in several parts. The other parts in this series are:

Part 1 General principles and requirements

Part 2 System aspects

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
