IS/IEC/TR 63042 : Part 303 : 2021 UHV a.c. Transmission Systems - Part 303 Measurement of UHV a.c. Transmission Line Power Frequency Parameter - Guidelines

NATIONAL FOREWORD

This Indian Standard (Part 303) which is identical to IEC TR 63042-303 : 2021 'UHV a.c. transmission systems - Part 303: Guideline for the measurement of UHV a.c. transmission line power frequency parameters' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the UHV Transmission System Sectional Committee and approval of the Electrotechnical Division Council.

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

a) Wherever the words 'International Standard' appears referring to this standard, they should be read as 'Indian Standard'; and

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.
