Example

When the impedances Z1, Z2, Z3 of a delta impedance circuit are 70, 35,

140respectively, obtain the impedances R1, R2, R3 of a Y circuit.

4.Press j to return to the PROG mode menu.

5. Press 0, select the program ‘DELTAY’
	(1)DELTA TO Y
and press e.
The direction of transformation will be	(2)Y TO DELTA
	X=?
asked.

6.Press 1 e to select ‘DELTA TO Y’ transformation.

7.Enter 70 for Z1, 35 for Z2 and 140 for Z3.

Result

The impedances R1, R2, R3 of the targeted Y impedance circuit are 10, 20 and 40, respectively.
