Understanding the Importance of Transformer Winding Relations

Three-phase transformers are crucial components in electric power systems, and their various configurations of winding relations play a significant role in determining their performance under different conditions, including when facing increased loads. The winding relations, such as Delta-Delta (DD), Wye-Wye (YY), Wye-Delta (YD), Delta-Wye (DY), Zig-Zag, and others, have unique characteristics that affect their efficiency, voltage regulation, and temperature rise.

Research on Transformer Winding Relations at the Electrical Energy Conversion Laboratory

Research conducted at the Electrical Energy Conversion Laboratory, Department of Electrical Engineering, Faculty of Engineering, University of North Sumatra, specifically examines the effect of increased load on efficiency, voltage regulation, and temperature rise on transformers with various winding relations. The study aims to reveal the secret of transformer belitan relationship in a state of load and provide valuable insights for the design and operation of electric power systems.

Revealing the Performance of the Belitan Relationship under Load Pressure

The results of the study showed that the DD0 winding relationship excelled in terms of efficiency, while the YY0 relationship demonstrated superior voltage regulation and the lowest increase in temperature. The findings indicate that the belitan relationship significantly affects the performance of transformers under load pressure.

Why Does the Belitan Relationship Affect Performance?

The difference in performance between various transformer winding relationships can be attributed to the effect of the belitan relationship on current and voltage. Understanding the underlying principles of the belitan relationship is essential to appreciate its impact on the performance of transformers.

Efficiency

The DD0 winding relationship has the best efficiency because it produces lower currents in the primary and secondary windings. Lower current means smaller loss of loss (heating losses), thereby increasing efficiency.

Voltage Regulation

The YY0 relationship excels in terms of voltage regulation because it has the ability to withstand changes in smaller output voltage when the load changes. This is caused by the effect of neutralization of the voltage at the neutral point of the Wye system.

Increase in Temperature

The lower temperature increase in the YY0 relationship is caused by lower currents and better heat distribution. The YY0 configuration allows the division of currents that are more evenly distributed between three phases, thereby minimizing heating at a specific point.

Implications for Electric Power Systems

The results of this study have significant implications for the design and operation of electric power systems:

Optimization of Efficiency

Understanding the efficiency characteristics of various winding relationships allows the selection of appropriate configurations to maximize energy efficiency and minimize power loss.

Voltage Settings

The use of a winding relationship that guarantees good voltage regulation is crucial to maintain stability and prevent damage to electrical equipment.

Operational Security

Understanding the belitan relationship's resistance to loads is more helpful in designing a safer system and minimizing the risk of damage due to overload.

Importance of Further Research

This study opens the way for further research to understand the effect of other factors such as the type of transformer, capacity, and non-linear burden on the performance of the winding relationships. By continuing to explore an understanding of the characteristics of the belitan relationship, we can increase the efficiency, reliability, and security of the electric power system, as well as maximize optimal energy utilization.
