Is there any calculation to find unknwon(unferroled) phases R Y B in alternator,3 phase motor anybod..

Answer / adk

Maximum This kind of unferroled problem will be faced in
rewinded motors & it can be identified by no of ties tied
for winding at near terminal box in a motor & can be noted
as RYB with that identification.

Answer / adk

IF we want to find only Particluar winding of a phase we
can check resistance of each winding Where the resistances
are equal then we can notice each phase end points but
which is starting & ending winding & RYB cannot be
identified With out ferroling by unknown user.
