Delta star, star-delta transformation with Ti-84 Plus (CE)
Delta->star and star->delta conversion program of an electric network
The Delta→Star and Star→Delta conversion of an electric network require intensives calculations. This program saves a lot of time and can be used for complex networks as well as DC systems with only resistors, making it very useful in electrical engineering.
See the schematics.
delta→star : N=Z12+Z23+Z31, Z1=(Z12*Z31)/N, Z2=(Z12*Z23)/N, Z3=(Z31*Z23)/N
star→ delta : T=Z1Z2+Z2Z3+Z3Z1, Z12 =T/Z3, Z23 = T/Z1, Z31 = T/Z2
