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.
