You can interconnect transformer windings in several ways to produce various output voltages. For power and distribution, you employ the conventional delta or wye connection. But for special applications, you can use an other lesser-known configuration: the zigzag connection. As you know mentioned phase shifting in IEC60076 is limited to multiple of 30 degree, but … Read More »https://electrical-riddle.com/wp-content/uploads/2021/08/810813014_813.gif
