Missing Citation
In the original publication [1], there was a mistake in the Figure 1 citation. The reference [2] was not cited. The citation has now been inserted in Section 2. Methodology, Subsection 2.1 Oil Wedge Definition, Caption of Figure 1, and should read:
2. Methodology
2.1. Oil Wedge Definition
The insulation system of a power transformer is very complex. Thus, manufacturers need to know the exact dielectric strength of each compound (dielectric material) in the system, as well as the electric field stress of each part (at each point). The structure of an insulating system is not ideal, which means that undesirable areas, such as oil wedges may exist. One of the most critical places for the occurrence of these small oil layers is the main duct of a power transformer, where the local electric field stress becomes very high. More precisely, the oil wedge may be located between a mounting rib and a pressboard barrier. An example of this phenomenon is shown in Figure 1 [2].
The subfigure on the left side of the figure, which shows the main insulation was cited from [2].
References Correction
In the original paper [1], reference [2] was missing, and has now been added in the reference list as ref. 14. With this correction, the order of several references have been adjusted accordingly. Now the manuscript presents 27 positions in the reference section.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
