Re: Henry's current transformer problem

 

From the available data we have not seen Br depending temperature change from 25¡ã C to 100¡ã C.

Thank you that looks like a good typical material to use.

My understanding is then that given that I am operating at only 50Hz with just some high frequency transients, that any core losses will be insignificant.

Then I can model in LTSpice the effects of ambient temperature using e.g.:

Hc = 22 at 25C decreasing by 0.12 % per C
Bs = 490m at 25C decreasing by 0.27 % per C
Br = 100m at 25C - Does this have a temperature coefficient?

Thanks and Regards
