What is BS EN 60076-2 - Liquid-immersed transformers about?
A liquid-immersed transformer is made up of a magnetic core, and coil assembly which is immersed in a fluid, mineral oil. The fluid must possess both good electrical insulating characteristics, and heat transfer characteristics. The liquid-immersed transformer permits a compact design.
BS EN 60076-2 applies to liquid-immersed transformers, identifies power transformers according to their cooling methods, defines temperature rise limits, and gives the methods for temperature rise tests.
Who is BS EN 60076-2 - Liquid-immersed transformers for?
BS EN 60076-2 on liquid-immersed transformers is helpful for:
- Manufacturing industries
- Power plants
- Transmission applications
- Military applications
Why should you use BS EN 60076-2 - Liquid-immersed transformers?
It is essential to have access to reliable requirements to install, and monitor the temperature of liquid-immersed transformers. BS EN 60076-2 guidelines provides manufacturers with the terms, definitions, cooling methods, normal cooling conditions, and temperature rise tests which allows them to effectively define, and maintain the temperature for liquid-immersed transformers.
What has changed since the last update?
BS EN 60076-2:2011 supersedes EN 60076-2:1997 which has been withdrawn. BS EN 60076-2:2011 includes the following significant technical changes with respect to EN 60076-2:1997:
- The standard is applicable only to liquid immersed transformers
- The winding hot-spot temperature rise limit was introduced among the prescriptions
- The modalities for the temperature rise test were improved in relation to the new thermal requirements
- Five informative annexes were added in order to facilitate the standard application
