WebK-factor is used by transformer designers to develop transformers made especially for non-linear loads and the extra heating caused by the harmonic currents. Transformers come in basic K-factors such as 4, 9,13, 20, 30, 40, and 50. The strategy is to calculate the K-factor for your load and then specify a transformer with a K-factor of an Web7 jun. 2024 · The comparison of the coil and the straight conductor shows how a transformer primary can be connected to a source and act to limit the current. The four factors that determine or control the inductance of a coil are the cross-section of the core, the number of turns, the type of the core, and the length of the coil.
