Losses Of  Transformer

 

A transformer is a device that moves electrical energy between circuits or between multiple circuits in electrical systems. The amount of energy lost during the transfer process determines a transformer's efficiency. There are two main categories of these losses: losses at the core and at the end.

The excitation of the transformer's core's magnetic fields causes core losses. The resistance of the core material and the magnetic field leakage through the core are the causes of these losses. Core losses are typically low, but they rise with input voltage frequency.

On the other hand, the resistance of the transformer's windings causes winding losses. These misfortunes are made by the warming of the windings due the progression of current. Core losses are typically lower than winding losses, and winding losses rise with winding current.

Loss of hysteresis: The core material's magnetization and demagnetization are the causes of it. The area of the hysteresis loop and the frequency of the applied voltage are directly related to this loss.

loss of eddy current: Circulating currents within the core are to blame. The shifting magnetic field is the cause of these currents, which consume energy. Eddy current loss is inversely proportional to the core's thickness and directly proportional to the square of the applied voltage's frequency.

Copper loss is another loss brought on by the resistance of the transformer winding. It rises in proportion to the winding's resistance and the amount of current passing through it.

Designers frequently employ high-quality core materials with low loss characteristics to reduce transformer losses and utilize high-purity copper to reduce winding resistance. The electrical system's overall efficiency can be improved by reducing transformer losses, which can result in significant energy savings.

In outline, transformer misfortunes are the energy that is lost during the exchange cycle. There are two main categories of these losses: core losses and winding losses, such as the loss of copper, eddy current, and hysteresis. Designers use high-quality core materials and reduce winding resistance to reduce transformer losses. This contributes to improving the electrical system's overall efficiency, resulting in significant energy savings.
