Example
When the impedances Z 1 , Z 2 , Z 3 of a delta impedance circuit are 70, 35,
140 respectively, obtain the impedances R 1 , R 2 , R 3 of a Y circuit.
4. Press j to return to the PROG mode menu.
5. Press 0, select the program ‘DELTAY’
and press e.
The direction of transformation will be
asked.
6. Press 1 e to select ‘DELTA TO Y’ transformation.
7. Enter 70 for Z 1 , 35 for Z 2 and 140 for Z 3 .
Result
The impedances R 1 , R 2 , R 3 of the targeted Y impedance circuit are 10, 20
and 40, respectively.
