Losses in the transformer

Web9 de set. de 2024 · Generally, these losses can be divided into two categories: magnetic, or core, losses, and I 2 R, or coil loss. The core losses are relatively constant, resulting from the magnetic circuit that does not change much as transformer current changes. Currents cause the I 2 R, or coil loss, and because currents change, so do the coil losses. WebIt is proposed in the paper to divide transformer losses into no-load and load losses, the former including core and dielectric losses, and the latter resistance and stray losses. The magnitude of the stray loss is shown in a large number of commercial transformers and in a few experimental machines. The relation between the impedance watts and the load …
