Hi Guys,

Kindly suggest me any circuit for detect phase reversal in 3-Phase system using microcontroller

If R-Y-B change (Eg. Y-R-B , R-B-Y )....

If you first establish that all three phases are present, you only need to compare two of them to establish the rotation.
You can do it with a 4013 (with suitable voltage scaling!)

Thanks for your reply

Yes, I need to compare two phase R-Y or Y-B or B-R
