Three phase transformer connections

Currently, the most common transformer connection methods are Y star and D deltawhile Z zigzag is not commonly used. Z represents the zigzag connection mode. The representation method of the transformer connection group is through capital letters for the primary side and lowercase letters for the secondary side.

Y or y indicates star connection, while D or d signifies delta connection. The phase relationship between the primary and secondary side voltages is denoted by a number using clock notation. The primary side voltage phasor corresponds to the minute hand, which remains fixed at the 12 o'clock transformer, while the secondary side line voltage phasor corresponds to the hour hand.

For instance, "yn, d11" means that the secondary side line voltage phasor is at the 11 o'clock position when the primary side line voltage phasor points to the 12 o'clock position as the minute hand. This indicates that the line voltage Uab on the secondary side lags behind the line voltage UAB on the primary side by degrees or leads by 30 degrees.

The two windings of the transformer can be combined to form four wiring groups: "Y, y", "D, y", "Y, d," and "D, d. Since Y connection can be made with or without a neutral wire, there is no symbol added when without a neutral wire, but hookups letter "n" is added after the letter Y for a connection with a neutral wire, indicating that the neutral point has hookups lead-out line. In the Vn0 wiring group, UAB and uab coincide, and the hour and minute hands point to 12, which is represented by "0" in the new wiring group notation.

It's possible to transformer a three-phase transformer's primary and secondary windings in numerous ways, depending on the number of terminals available and your specific application. Three-phase power is produced, transmitted, and distributed in a power system network. As a result, three-phase transformers are required to alter voltage levels in a three-phase system.

A three-phase transformer has two types of three-phase windings - primary and secondary. The primary and secondary windings can be linked together in a star Wye or delta configuration. Depending on the application, a transformer's primary and secondary winding will feature four different connections.
