distributionsfaktor

Distributionsfaktor, also known as distribution factor or blocking factor, is a term used in the context of electrical engineering, particularly in the analysis of transformers. It quantifies the reduction in the electromotive force (EMF) induced in a winding due to the non-uniform distribution of coils within a magnetic slot. When coils of a winding are not placed adjacently in the slots but are instead distributed, the EMF induced in each coil segment will be slightly out of phase with the EMFs induced in other segments. This phase difference leads to a net reduction in the total EMF of the winding compared to an ideal scenario where all coils are perfectly aligned.

The distributionsfaktor is typically a value less than one, and it is calculated based on the geometry of the winding and the number of slots occupied by the coils. A lower distributionsfaktor indicates a greater reduction in induced EMF. This factor is important in transformer design as it affects the voltage regulation, the leakage reactance, and the overall efficiency of the transformer. Engineers use the distributionsfaktor to accurately predict the performance of transformers and to optimize their design for specific applications. It is a crucial parameter in ensuring that transformers operate reliably and efficiently under various load conditions.
