IEC 60076-11:2018 RLV

Power transformers - Part 11: Dry-type transformers

OVERVIEW

IEC 60076-11:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.



IEC 60076-11:2018 applies to dry-type power transformers (including auto-transformers) having values of highest voltage for equipment up to and including 72,5 kV and at least one winding operating at greater than 1,1 kV. This document does not apply to:

- gas-filled dry-type transformers where the gas is not air;

- single-phase transformers rated at less than 5 kVA;

- polyphase transformers rated at less than 15 kVA;

- instrument transformers;

- starting transformers;

- testing transformers;

- traction transformers mounted on rolling stock;

- flameproof and mining transformers;

- welding transformers;

- voltage regulating transformers;

- small power transformers in which safety is a special consideration.

Where IEC standards do not exist for the transformers mentioned above or for other special transformers, this document may be applicable as a whole or in parts. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. The main changes with regard to the previous edition are as follows:

- Extension of the scope up to 72,5kV

- Enclosure management in regards of the performance

- Management of the dielectric and thermal features with altitude

- New climatic classes for a better adaptation of customers’ need

- Establishment of the relation between location and environmental classes

- For fire behaviour classes, limitation at 1000kVA and process of test more robust

- Introduction of Seismic class

- Recommendations for amorphous transformers

Keywords: dry-type transformers
