Star-Delta Transformations

Star delta transformation

in this delta diagram R12 lie between 1 and 2 ,R23 lie between 2 and 3 ,R31 lie between 1 and 3.

NOTE – Star is also know as (T) and delta is known as (∏)


First let us check out the delta to star conversion:-

Now The Solution :-

R1=       R13 × R23/R13 + R23 + R12

R2 =      R12 × R13/R13 + R23 + R12

R3 =      R23 × R12/R13 + R23 + R12



Now star to delta conversion

Now the solution ÷

R31 = R1 + R3 + (R1 ×R3/R2)

R12 = R1+ R2 + (R1 × R2/R3)

R32 = R3 + R2 + (R3 × R2/R1)
