Consider a Δ-Y transformer with the following winding resistance measurements taken in the field:

R

_{X1-X2}: 2.667

^{mΩ}

R

_{X2-X3}: 2.672

^{mΩ}

R

_{X3-X1}: 2.645

^{mΩ}

R

_{H1-H2}: 2.428

^{mΩ}

R

_{H2-H3}: 2.315

^{mΩ}

R

_{H3-H1}: 2.445

^{mΩ}

Note: Aside from X1, X2, X3 and H1, H2, H3 terminals, all other connections are inaccessible with the X

_{0}buried.
