Propagation of high frequency overvoltages in transformers

2014 ICHVE International Conference on High Voltage Engineering and Application, 2014
In modern grids and networks more and more switching and reconfiguration operations are present. In addition external stresses like lightning may cause overvoltages. Thus, such transients may subject the electric insulation system of power equipment.

Design and Thermal Analysis of a High-Voltage High-Frequency Transformer

IECON 2025 – 51st Annual Conference of the IEEE Industrial Electronics Society
High-voltage high-frequency (HVHF) transformers are one of the crucial components in HVDC power supplies. However, they occupy more space, and compared to other components in the system, they experience more energy losses. HVHF transformers need special attention to both thermal and electrical properties, mainly because of the use of ferrite cores ...

High-frequency power transformer modeling

2013
The detailed study of high-frequency over- voltages propagating inside the electrical systems of a power plant requires a precise modeling of power transformers at high frequencies. These over- voltages may originate from lightning overvoltage propagating along the transmission line and crossing the step-up transformer, they may originate also for ...
