Abstract

This paper demonstrates how to find optimal threshold values for the cooling system of power transformers in respect to minimize the total loss consumption and maximise the life span without adding extra maintenance costs. To reach this ambition the transient thermal behaviour of a power transformer is studied for different ambient temperature scenarios together with the moisture behaviour over a complete life cycle, an essential parameter to determine the aging condition of the cellulosic insulation.

  1. 1.

    It can be also seen in the right part of the figure, that a moisture decrease during a heating process is faster than the moisture increase during a cooling process.
