ECE 3301 General Electrical Engineering Presentation 11 Delta – Wye Conversion

Delta-to-Wye Conversion Some arrangements of resistances are neither in parallel nor in series.

Delta-to-Wye Conversion Two such arrangements are the delta and wye connection.

Delta-to-Wye Conversion A transformation from the delta connection to the wye connection may be derived by considering the resistance from point A to point B in the wye connection.
