WebMar 14, 2014 · As shown in Figure 4, one transformer is a delta-zigzag configuration harmonic mitigating transformer with a 0-deg phase shift, and the second transformer is a delta-wye with a 30-deg phase shift. Voltage distortion is normally greatest at the point where the equipment is connected to the distribution system.

Characteristics and Uses of Zig-Zag and Wye-Delta Grounding Transformers
I know you said but it's important to understand the mathematical foundation, so I'll explain it first. There're two types of problems related to vector groups: 1) given the connection diagram of the Tx and the phase sequence of the system, get the vector group; 2) given the vector group and the phase sequence … See more To understand why the phase shift happened, simply recap what we did when deducing the angle by which a line-to-line voltage on the LV side lags the corresponding line-to … See more Above I assumed you meant that \$ \tilde V_{{\text{LL}}_\text{s}} \$ lags \$ \tilde V_{{\text{LL}}_\text{p}} \$ by 30° (which is equivalent to saying \$ \tilde V_{{\text{LL}}_\text{p}} … See more WebA common application of transformer differential relays is the protection of a delta-wye power transformer. The current entering the primary side of the transformer is compared to the current leaving the secondary side. The transformer causes a phase shift between the primary and secondary currents, which must be accounted for in the relay ... originlab 2019b crack
