BS IEC 60076-15:2015

What is BS IEC 60076-15 – Power transformers about? 

BS IEC 60076-15 is an international standard that discusses gas-filled power transformers. Gas-filled power transformers is a transformers of which the magnetic circuit and windings are placed in an enclosure filled with an insulating gas. 

BS IEC 60076-15 applies to three-phase and single-phase gas-filled power transformers with the exception of certain categories of small and special transformers such as: 

• Single-phase transformers with rated power less than 1 kVA and three-phase transformers less than 5 kVA 
• Transformers, which have no windings with a rated voltage higher than 1 000 V 
• Instrument transformers 
• Traction transformers mounted on rolling stock 
• Starting transformers 
• Testing transformers 
• Welding transformers. 

Who is BS IEC 60076-15 – Power transformers for? 

BS IEC 60076-15 on gas-filled power transformers applies to: 

• Manufacturer of power transformers 
• Quality testing personnel 
• Electrical engineer 

Why should you use BS IEC 60076-15 – Power transformers? 

Gas-filled power transformers is a transformers of which the magnetic circuit and windings are placed in an enclosure filled with an insulating gas. 

BS IEC 60076-15 provides the safety, environmental requirements for gas leaks in the transformer manufacturers that consider the effective containment of the gas of the transformer and take effective measures to prevent leakage. Consideration is given to the long-term performance of items such as: 

• Joint Design 
• Gasket materials 
• Welds 
• Corrosion prevention. 

The power transformers are designed to be leak-free and any leakage found on-site at the end of commissioning is corrected by the responsible suppliers by using BS IEC 60076-15.
