WebJan 6, 2024 · The line conductors connect to each point where two windings meet. This system is called a “Delta” because when it’s drawn out it looks like a triangle (the Greek symbol Delta for the letter D). For a delta/delta transformer, both the primary and secondary windings are delta connected (Fig. 1). Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers.

In 240 V systems, the customers are served by several low-voltage feeders, realized by overhead power lines, aerial or underground power cables, or their mixture. WebA single-phase transformer treats power lines as an input source. It uses two windings (primary and secondary) for changing the voltage. A three-phase transformer, on the other hand, uses three windings (wye, mesh, and zigzag). These are coils joined in the precise sequence to match the incoming voltage and maintain accepted polarity and phasing.
