The HV and LV winding is wound around the central limb. The central limb carries the entire flux (Ф ). The flux (Ф ) divides into two equal part and thus each side limbs carries the half (Ф/2 ) of the total flux(Ф ). As a result, cross section area of the central limb is two times of the side limbs area.The arrangement of the winding around the central limb is as given below.
The maximum current a transformer can deliver to loads at the rated voltage is known as a transformer rating. It is expressed in VA, kVA, … Read more

When two single-phase transformer is connected in an open delta connection, the arrangement can provide a three-phase supply to the load. The open delta connection … Read more
The transformer can be categorized into core type and the shell type.In a core type transformer the winding encircles the core whereas in a shell type transformer the core encircles the winding. The winding encircles the core of a transformer. The Single phase transformer has two limbs and three phase transformer has three limbs.
