BS EN 60076-2:2011

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BS EN 60076-2:2011 supersedes EN 60076-2:1997 which has been withdrawn.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
