IntroductionIntroduction
In the electrical Power industry Distribution
Transformers play a major role.
In design point of view, loss and cost reduction
should be ma or considerations.
To achieve a optimized design, manufacturers
require proper transformer design manuals.
For a given transformer capacity, the designmanual should be
capable of giving the most
appropriate directives and guide lines.
