How efficient is the transformer? Why is there loss when the transformer is running? Next, please ask the staff of baoding dry type transformer manufacturer to analyze the transformer operation efficiency and loss.

At rated power, the ratio of output power and input power of the transformer is called the efficiency of the transformer, i.e.

Eta = P1 / P2,

In the formula, replacing is the transformer efficiency; P1 is the input power and P2 is the output power.

When the output power of the transformer P2 is equal to the input power P1, the efficiency power is equal to 100%, and the transformer will not produce any loss. However, in practical application, this kind of transformer is not available, that is to say, the transformer will generate losses in operation.

The loss of power transmission in transformer mainly includes copper loss and iron loss. The details are as follows:

A, copper loss

The copper loss of the transformer refers to the loss caused by the resistance of the transformer coil (the transformer coil is usually made of insulated copper wire). The reason for this is that when the current heats up through the resistance of the coil, some of the electrical energy is converted into heat and lost.

Second, the iron loss

The iron loss of transformer mainly includes two aspects, one is hysteresis loss, the other is eddy current loss. The causes of iron loss are as follows:

1. Hysteresis loss

The hysteresis loss is the loss caused by the change of direction and size of the magnetic force line of the silicon steel sheet through the transformer when the alternating current passes through the transformer.

2. Eddy current loss

When the transformer is working, magnetic force lines pass through the iron core, and induced current will be generated on the plane perpendicular to the magnetic force line. As this current forms a closed loop and forms a vortex, it is called eddy current. The existence of eddy current causes the core to heat and consume energy, that is, eddy current loss.

To sum up, the efficiency of transformer is closely related to the power of transformer. Generally, the higher the power of transformer, the smaller the ratio of loss to output power and the higher the efficiency. Conversely, the lower the power, the lower the efficiency.
