What is a winding transformer?

Zigzag Transformer is a three -phase device that creates a ground reference point from a three -wire three -phase power line. It decreases into the category of three -phase transformers and uses a special design that derives a new set of three -phase vectors from the existing three -phase vectors, which controls a star or interconnecting Y. To describe a three -phase zigzag transformer, it may be useful to look at a simple single -phase and double phase. When a living wire with one phase is disrupted or without a failure, the neutral wire is always on the same potential. Although the power feeder is rarely used, its principle is a good reason to describe the role of a winding grounding transformer. If it existed, a double phase feeder would use two live wires with a vector phase shift 180 degrees from the second. If double-picase electrical transformers are considered, the distribution of a double phase of 110 volts (VAC) would use two 110 Vac Live Wires each with 110 VAC to Neutrral.

In the above example, it also believes that the neutral or ground line was not available. It should be noted that the neutral point is accessible on the side of the generator, where the center click at the 110-0-110 generator output. The challenge is to create a neutral wire downstream in distribution. Again, the double counterpart of the Zigzag transformer will have two windings with a joint connection with the neutral and other ends of the winding will be associated with two live wires. If the load of each phase of the double phase feeder is balanced, it will be between the zigzag neutral between the winding difference; Otherwise, the non -zero tensionzigzag will be neutral to the ground.

Zigzag transformer, which is a star or y-connection, regenerates the three-phase output by means of two phases voltage at a time. When all combinations of two phases have been made, the resulting three -phase vectors are convergent in one reference neutral point. Inside the winding transformer there are two sets of winding for each phase - internal winding and outer winding - which are contradictory for the opposition of the flow. For each core, the inner winding is removed from the next phase in the sequence. When the load is balanced on each of the three phases, the neutral point of the winding transformer is on the same potential as the soil, but when there is a failure in the phase or imbalance at the phase load, the neutral point will be tension.
