Self-Induced EMF in Primary Side Solution

STEP 0: Pre-Calculation Summary

Formula Used

Self Induced EMF in Primary = Primary Leakage Reactance*Primary Current
E_self(1) = X_L1*I₁
This formula uses 3 Variables

Variables Used

Self Induced EMF in Primary - (Measured in Volt) - Self induced emf in Primary is the electromagnetic force induced in the Primary winding or coil when the current in the coil or winding changes.
Primary Leakage Reactance - (Measured in Ohm) - Primary leakage reactance of a transformer arises from the fact that all the flux produced by one winding does not link with the other winding.
Primary Current - (Measured in Ampere) - Primary Current is the current which is flow in the primary winding of the transformer. The primary current of the transformer is dictated by the load current.

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.
