     At rated power, the ratio of the output power of the transformer to the input power is called the efficiency of the transformer, that is,where η is the efficiency of the transformer; P1 is the input power, and P2 is the output power.

   When the output power P2 of the transformer is equal to the input power P1, the efficiency η is equal to 100%, and the transformer will not produce any loss. But in fact there is no such transformer. When a transformer transmits electrical energy, losses are always generated, which mainly include copper loss and iron loss. Copper loss refers to the loss caused by the resistance of the transformer coil. When the current passes through the coil resistance to generate heat, a part of the electrical energy is converted into heat energy and lost. Since the coil is generally wound with insulated copper wire, it is called copper loss.

   The iron loss of the transformer includes two aspects. One is the hysteresis loss. When the AC current passes through the transformer, the direction and size of the magnetic field lines passing through the silicon steel sheet of the transformer change accordingly, causing the molecules inside the silicon steel sheet to rub against each other and release heat energy, thus losing a part of the electrical energy, which is the hysteresis loss. . The other is eddy current losses, when the transformer is operating. There are magnetic lines of force passing through the iron core, and an induced current will be generated on a plane perpendicular to the magnetic lines of force. Since this current forms a closed loop to form a circulating current and is vortex-like, it is called an eddy current. The existence of eddy current makes the iron core heat up and consumes energy, and this loss is called eddy current loss.

    The efficiency of the transformer is closely related to the power level of the transformer. Generally, the greater the power, the smaller the ratio of loss to output power, and the higher the efficiency. Conversely, the lower the power, the lower the efficiency.
