A Delta-Star Transformation Approach for Reliability Evaluation
Hariom Gupta, Jaydev Sharma · IEEE Transactions on Reliability · 1978
This paper presents new exact expressions for delta-star transformation to simplify complex reliability block diagrams consisting 2-state or 3-state devices. The conditions are given under which the transformation applies. The expressions are interrelated and require less computation time for finding equivalent star configuration. Expressions can also be derived for star-delta transformation in the same way.
