Flux density calculation in transformer

WebWhat is flux in transformer? In a transformer, the magnetic flux created by the primary coil induces a current in the core. This occurs in order to oppose the charge that produced the magnetic flux (Lenz's Law). The currents flowing in the core are called eddy currents. These currents produce heat, using up energy and so causing inefficiency. WebAug 14, 2024 · The formula method uses the fundamental transformer equation to calculate the effective flux density for a particular value of fault current. The calculated flux density is then compared to the capability of the steel used in the core of the CT and a determination is made whether the core will saturate or not for that fault current.
