How to Reduce Transformer Core Losses?

Transformer core losses primarily include eddy current losses and hysteresis losses. Here is an elaboration on methods to decrease core losses:

Optimize core material: To minimize losses, selecting core materials with low losses and high saturation magnetic induction is crucial. Silicon steel is currently one of the most widely used materials for transformer cores, and its silicon content effectively reduces eddy current losses.

Employ laminating techniques: Transforming silicon steel into laminated sheets can effectively slow down the formation and propagation of eddy currents, thereby reducing loss levels. This laminating technique contributes to enhancing the performance of the core and reducing energy losses.

Utilize cooling techniques: By employing cooling techniques such as oil cooling or air cooling, it is possible to maintain the transformer's temperature within an appropriate range. Maintaining the right temperature helps decrease hysteresis losses, enhancing the operational efficiency of the equipment.

By comprehensively applying these methods, it is possible to effectively reduce transformer core losses, improving the efficiency and reliability of the equipment. These measures not only contribute to lowering energy consumption but also aid in extending the lifespan of the equipment.
