The way towards 800 kV DC converter transformers | Think Grid manufacturers, however, it is not simply a matter of scaling up the structure. Today, GE offers 800 kV converter transformers, but as David Wright, Senior Expert Engineer in the Power Transformer Division, explains, "Developing UHVDC systems meant practically starting from scratch in many cases.

Modeling of Ion Injection in Oil-Pressboard Insulation Systems:541364/FULLTEXT01.pdf· PDF fileFigure 1. Picture of an UHVDC transformer. Photo: ABB The conversion from AC to UHVDC and back is very costly and this is why the DC transmission becomes favorable over long distances. To convert AC into HVDC, DC converters are used in conjunction with power transformers. One such converter transformer is presented in Figure 1.

A precise ultra high frequency partial discharge location ... many countries, sensors are typically installed in GIS. In China, however, external antennas are used. Because external antennas are used to detect the weak electromagnetic waves from PDs that leak from the insulation gap of the GIS, the signal is weak and needs to be filtered using a suitable algorithm.Author: Jiajia Song, Jinbo Zhang, Xinnan Fan
