SUMMARY
The discussion focuses on selecting the optimal core material for building current transformers to generate power from a 7kV power line. Silicon-Steel, particularly a 3% Si-Fe composition, is identified as providing high flux density saturation, while a 50% Co-Fe composition is also noted for its potential to enhance power output. The conversation emphasizes that ferrite cores are not suitable for 50/60Hz applications due to significant eddy current losses. Additionally, concerns regarding heat generation from resistive wire losses and eddy current losses in the laminated core are raised.
