Calculation of transformer no-load loss, load loss and impedance voltage
This article elaborates on the composition, calculation method and related factors of transformer loss. Iron loss and copper loss are fixed loss and variable loss of transformer respectively. The article gives the calculation formulas of active loss, reactive loss and comprehensive power loss, as well as the selection conditions of each parameter. Then, the characteristics of transformer loss are discussed, including the composition and influencing factors of no-load loss and load loss.
