Introduction to the four basic types, starting with the "Y-Δ (Y-Delta) method"!
There are various connection methods for three-phase transformers, but I will introduce the four basic types among them. Starting with the "Y-Δ (Wye-Delta) method," which is mainly used as a step-down transformer, there are also the "Δ-Δ (Delta-Delta) method" and the "Δ-Y (Delta-Wye) method," as well as the "Y-Y (Wye-Wye) method," which are primarily used in circuits requiring high current. 【Lineup】 ■ Y-Δ (Wye-Delta) method ■ Δ-Δ (Delta-Delta) method ■ Δ-Y (Delta-Wye) method ■ Y-Y (Wye-Wye) method *For more details, please refer to the PDF document or feel free to contact us.

**Features** ■Y-Δ (Y-Delta) Method - Mainly used as a step-down transformer - The third harmonic component of the excitation current circulates in the Δ circuit and does not flow out externally ■Δ-Δ (Delta-Delta) Method - Mainly used in circuits that require large currents - The winding conductors of the transformer can be made thinner - With the Δ circuit, it can absorb third harmonic current, preventing distortion of magnetic flux and induced electromotive force ■Δ-Y (Delta-Y) Method - Mainly used as a step-up transformer - The third harmonic component of the excitation current circulates in the Δ circuit and does not flow out externally ■Y-Y (Y-Y) Method - Not commonly used *For more details, please refer to the PDF document or feel free to contact us.*
