The discussion focuses on calculating core losses in a toroid core, specifically for a 150 x 100 x 60 M4 grade toroid core. Participants emphasize the importance of consulting the manufacturer's data sheet and application notes for accurate loss calculations. Key factors influencing core losses include the frequency range, voltages, currents, and the specifics of the transformer design. The conversation highlights the risks associated with high voltage projects, particularly for beginners.
PREREQUISITESElectrical engineers, transformer designers, and beginners interested in high voltage applications who seek to understand core loss calculations and safety considerations.
It sounds like this is related to your other two recent threads about transformers:Sudalai said:Hello!
I want your help for core losses on how to calculate core loss on a toroid core?
You have not responded to my questions in your thread with the above post. You really need to give us much more information about this project if we are to help you.Sudalai said:I have 150 x 100 x 60 M4 grade toroid core and same grade slit coil, I need to 180 x 100 x 60 in my design purpose.i would like to add OD 20 mm. my suspicion is a slit that can be added should be on the same grade?
That sounds a bit like a dangerous project for somebody who is a "beginner". What experience do you have working with AC Mains voltages like 230Vrms? What about high voltages like 4000V? Are you working with anybody who does have experience with those voltages and how to keep the project safe?Sudalai said:Sorry for the inconvenience, I need 4000 voltage for in our testing purpose but I have single phase variac 240 v so I would like to design step up 230: 4000v I am is a beginner for designing so I am struggling that
We still need answers to these questions in order to try to help you. Thank you.berkeman said:What frequency range will your transformer operate within? What voltages, currents, powers, temperature range, etc.? Can you clarify the size and materials and construction details? What do the source and load look like for this transformer? How reactive are they?
