Transformer Losses | Core loss | Copper loss | Eddy Current loss | Hysteresis Loss

What are the losses of the transformer?


 here are two main types of transformer loss: -

 Core loss

 Copper loss 

transformer

Core loss Two types: -

Eddy current loss

Hysteresis loss


Copper loss Two types: -

Copper loss in the primary winding 

Copper loss in the secondary winding

Eddy current loss and hysteresis current loss The following is the


Eddy loss:

When the current flowing through the coil of an electromagnet changes. Then the magnetic field around it also changes This variable flux cuts the wire of the coil, creating voltage in the coil This flux also cuts the same core As a result, a current is also rotated in this core, called eddy current The core resistance is interrupted when the eddy current flows through the core material. The waste that causes it is called eddy current loss


Ways to reduce Eddy ​​current loss: - 

This loss can be reduced by using a thin core of bright resistive magnetic material.



Hysteresis Loss:

The variable current changes direction every half cycle As a result, the magnetic flux changes periodically to the maximum positive meaning once and the maximum negative value again. This periodic change of positive mean and negative mean causes the core magnets to change direction again and again. Power is expended as a result of so much collision. This expended energy appears as heat, this is called hysteresis loss.


Ways to reduce hysteresis loss: -

This loss can be reduced by using high-quality magnetic steel core.


Effects of hysteresis loss: -

The higher the hysteresis loss, the more heat will be generated As a result power loss will increase and insulation will be more damaged.
