How do I calculate eddy current losses in mains transformers?

Click For Summary
SUMMARY

This discussion focuses on calculating eddy current losses in 50Hz mains transformers, specifically in relation to lamination sizes. The user seeks relative figures for comparison rather than precise measurements. A reference link to a relevant article on using power transformers at unintended frequencies is provided, indicating that existing resources may not adequately address the user's needs.

PREREQUISITES
  • Understanding of eddy current losses in electrical engineering
  • Familiarity with transformer design principles
  • Knowledge of lamination materials and their impact on performance
  • Basic grasp of frequency effects on transformer operation
NEXT STEPS
  • Research methods for calculating eddy current losses in transformers
  • Explore the impact of lamination thickness on eddy current losses
  • Learn about materials used in transformer core construction
  • Investigate the effects of operating transformers at non-design frequencies
USEFUL FOR

Electrical engineers, transformer designers, and students studying power systems who are interested in optimizing transformer efficiency and understanding loss mechanisms.

Hi all i hope some one can help but i have a feeling there will be no easy calculations for this one:confused:
Im trying to calculate actual eddy current losses in 50hz mains transformers depending on lamination sizes and can't seem to find any info on the subject that's sub electrical degree level. I am not looking to produce figures accurate to a milliwatt just relative numbers for comparison purposes

Can anyone help?
Thanks in advance
Harry
