Delta (Δ) – Wye (Y) conversion
Such configurations may frequently be handled by the use of Δ −Y or Y −Δ transformation. One of the most fundamental 3-terminal network equivalents is that of three resistors associated in “Delta (Δ)” and in “Wye (Y)”. Such two circuits specified in the first figure above and the second figure above are at times part of a larger circuit and obtained their names from their configurations. Such three terminal networks can be redrawn as 4-terminal networks as shown in figures above. We can acquire helpful expression for direct transformation or conversion from Δ to Y or Y to Δ by considering that for equivalence the two networks containing the same resistance whenever looked at the similar pairs of the terminals.
