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

.
The direction of transformation will be
asked.
6.
Press

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.
