Study Of How To Separate The Losses Of Hysteresis And Eddy Current In The Distribution Transformer
Revealing the mystery of losses in the distribution transformer: Returning Hysteresis and Eddy Current
Transformers are static electrical devices that play a crucial role in distributing electrical energy. They work based on the principle of electromagnetic induction, using a magnetic field to move and change the alternating current voltage from one circuit to another. Transformers are essential components in the electrical grid, and understanding their losses is vital for optimizing their performance.
Transformers generally consist of layered iron cores and two coils, namely primary and secondary coils. Both of these coils are not directly connected, but magnetically. However, in this transformation process, there is a "loss" of energy that is converted into heat. This heat is known as the loss of transformers, and the main source is the iron core and copper coil.
Tracing the source of losses
Iron core losses
The iron core is a critical component of a transformer, and its losses are a significant contributor to the overall energy loss. There are two types of iron core losses: Hysteresis loss and Eddy Current loss.
*** Hysteresis loss: ** These losses arise due to the magnetic nature of imperfect iron core. When the magnetic field changes, iron molecules follow the field changes by producing heat. The faster the change in the magnetic field, the greater the heat produced. Hysteresis loss is a significant contributor to the overall energy loss in a transformer.
*** Eddy Current losses: ** Eddy current (Eddy Current) occurs when the iron nucleus is flowed back and forth. This current flows in a closed circle in the nucleus, producing heat due to material resistance. The form of layered iron core helps minimize this vortex current. Eddy Current loss is also a significant contributor to the overall energy loss in a transformer.
Copper coil losses
The copper coil is another critical component of a transformer, and its losses are also a significant contributor to the overall energy loss. There are two types of copper coil losses: Joule losses.
*** Joule losses: ** These losses are caused by resistance of copper coils. When the current flows through the coil, electrical energy is converted into heat due to resistance. The greater the current flowing, the greater the heat produced. Joule loss is a significant contributor to the overall energy loss in a transformer.
Understanding the importance of separation of losses
Understand and separate the two types of losses in the iron core, namely the losses of Hysteresis and Eddy Current losses, very important in the design and optimization of the transformer. This separation allows us to:
Analyze the efficiency of the transformer
By knowing the type and amount of losses, we can determine how efficient the transformer is in changing electrical energy. Understanding the efficiency of a transformer is crucial for optimizing its performance.
Minimizing losses
Knowledge of the sources of losses allows us to apply design solutions that minimize the heat generated. For example, the use of iron core materials with low coertivity can reduce the losses of hysteresis. Minimizing losses is essential for extending the lifespan of a transformer.
Increasing the resistance of the transformer
Excessive losses can cause damage to the transformer. By minimizing losses, we can increase the resistance of the transformer to heat and extend its use. Increasing the resistance of a transformer is crucial for ensuring its reliability.

Predicting efficiency, durability, and life life more accurately. Predicting the performance of a transformer is crucial for optimizing its design.
Speed ​​up the design process
Allows designers to explore various iron and material core configurations virtually before making prototypes. Speeding up the design process is essential for reducing the development time of a transformer.
Developing new technology
Opening the way for the development of new materials with better magnetic nature, so as to produce a more efficient and durable transformer. Developing new technology is crucial for improving the performance of transformers.
Through a deep understanding of transformer losses, especially in separating the losses of hysteresis and Eddy Current, we can maximize the efficiency and resistance of the transformer, and contribute to the efficiency of the overall use of electrical energy. Understanding transformer losses is essential for optimizing their performance and ensuring their reliability.
