Star-delta transformation of inductors - definition
The star and delta circuits shown in the figures are interconvertible. The equivalent value of inductance for star to delta transformation is: LRS=LTLRLS+LSLT+LRLT LRT=LSLRLS+LSLT+LRLT LST=LRLRLS+LSLT+LRLT The equivalent value of inductance for delta to star transformation is: LR=LRS+LRT+LSTLRSLRT LS=LRS+LRT+LSTLRSLST LT=LRS+LRT+LSTLSTLRT
