Ultra HVDC Transmission System· PDF filewith silicone housing installed by the bushing manufacturer HSP is now in successful operation since 1991. The hydrophobic properties prevent building up a conductive layer on the polluted insulator surface. Based on excellent experiences gained in various converter stations, the creepage distance can be reduced to 75% of the corresponding
IET Generation, Transmission & Distribution this study, a wide range of constant load temperature-rise tests were carried out on an 11/0.433 kV distribution transformer to study the dynamic thermal behaviour of the top-oil temperature. A model based on the IEC 60076-7 thermal model but with an improved oil time constant calibration was deduced for top-oil temperature modelling.

A Modular Multiport Power Electronic Transformer With ...&arnumber=6948256Abstract: This paper proposes a power converter architecture for the implementation of an ultrafast charging station for electric vehicles (EVs). The versatile converter topology is based on the concept of the power electronic transformer. For the direct transformerless coupling to the medium-voltage grid, a cascaded H-bridge (CHB) converter is utilized.
