The reactive power loss of the transformer is also divided into two parts: reactive power constant loss and reactive variable loss.
1. Active loss. It is approximately equal to the product of the nominal copper loss and the squared ratio of the apparent current (load current) to the rated current. Namely: active variable loss = rated copper loss × (load current / rated current) squared.
2. Reactive variable loss. It is approximately equal to the product of the rated short-circuit voltage percentage and the rated capacity and the square of the (load current) to the rated current. Namely: reactive variable loss = rated short-circuit voltage percentage × rated capacity × (load current / rated current) squared.
What is the relationship between hysteresis loss and hysteresis loss? The answering transformer is composed of a wire and an iron core. When the wire is generated during operation, the wire generates heat, and the eddy current generates heat. The heat released in the form of heat is called active loss. The hysteresis means that there is no conversion of residual magnetism. The heat loss caused by the electricity of the secondary coil.
In fact, electricity, magnetism, and light are all forms of electromagnetic waves.
