NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical with IEC 61850-3 : 2013 ‘Communication networks and systems for power utility automation - Part 3: General requirements’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Power System Control and Associated Communications Sectional Committee and approval of the Electronics and Information Technology Division Council.

This standard is one of the parts of a series of standards on ‘Communication networks and systems for power utility automation’. The other parts in this series are:

Part 1 Introduction and overview

Part 2 Glossary

Part 4 System and project management

Part 5 Communication requirements for functions and device models

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology 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.
