What is hysteresis loss in no-load loss?
Hysteresis Loss：
Definition: Hysteresis loss is the energy loss caused by the reversal and friction of magnetic domains when the core material is repeatedly magnetized and demagnetized in an alternating magnetic field.
Reason: In an alternating magnetic field, the orientation of magnetic domains in the core material changes with the variation of the magnetic field, and energy is consumed during this process.
Influencing Factors: Hysteresis loss is related to the hysteresis loop of the core material. The larger the area of the hysteresis loop, the greater the hysteresis loss. Commonly - used low - loss core materials include silicon - steel sheets and amorphous alloys.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
