Equivalent Reactance of Transformer from Primary Side Formula

Equivalent Reactance from Primary = Primary Leakage Reactance+Reactance of Secondary in Primary
X01 = XL1+X'2

What type of winding is used in a transformer?

In core type, we wrap the primary, and secondary windings on the outside limbs, and in shell type, we place the primary and secondary windings on the inner limbs. We use concentric type windings in core type transformer. We place a low voltage winding near the core. However, to reduce leakage reactance, windings can be interlaced.
