IS 2026 : Part 10 : 2025/IEC 60076-10 : 2016 Power Transformers - Part 10 Determination of Sound Levels
NATIONAL FOREWORD
This Indian Standard (Part 10) (First Revision) which is identical to IEC 60076-10 : 2016 'Power transformers - Part 10: Determination of sound levels' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Transformer Sectional Committee and approval of the Electrotechnical Division Council.
This standard was first published in 2009. This revision has been undertaken to align with the latest version of IEC 60076-10 : 2016.
This standard is published in various parts. Other parts in this series are:
| Part 1 | General |
| Part 2 | Temperature-rise |
| Part 3 | Insulation levels, dielectric tests and external clearances in air |
| Part 4 | Terminal markings, tappings and connections |
| Part 5 | Ability to withstand short circuit |
| Part 6 | Reactors |
| Part 7 | Loading guide for oil-Immersed power transformers |
| Part 8 | Application guide |
| Part 10/Sec 1 | Determination of sound levels, Section 1 Application guide |
| Part 11 | Dry-type transformers |
| Part 12 | Loading guide for dry-type power transformers |
| Part 14 | Liquid-immersed power transformers using high-temperature insulation materials |
| Part 15 | Gas-filled power transformers |
| Part 16 | Transformers for wind turbine applications |
| Part 18 | Measurement of frequency response |
| Part 19 | Rules for the determination of uncertainties in the measurement of the losses on power transformers and reactors |
| Part 21 | Standard requirements, terminology and test code for step-voltage regulators |
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'; 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.
