Power transformers play an important role in the electricity distribution chain. There are
several different types of transformers availiable on the market, but they basically consist
of only a few main components. The shape of the tank, which is a part of the transformer
housing, has a significant impact on the required amount of transformer oil.
The master’s thesis discusses evaluation of the transformer tank design. Through the
review and analysis of power transformers, key parameters have been determined, which
can be used to define and evaluate different tank designs, both from economic and
technical point of view. Construction guidelines and recommendations have been made
based on estimates of oil mass savings, tank manufacturing cost and profitability of the
shape of the tank.
