Experimental Study of Clamping Pressure during Step Loading of Power Transformer with and without Prior Energisation
Madshaven, Inge; Enoksen, Henrik; Lundgaard, Lars Esben; Jaufer, Stefan; Krause, Christoph; Prasnikar, Borut; Mjelve, Asgeir (Peer reviewed; Journal article, 2024)The electrification of society, increasing renewable energy sources and mobility charging lead to new loading patterns for power transformers. Dynamic load conditions induce enhanced mechanical stress on the transformers’ ... -
High-Frequency Resonant Overvoltages in Transformer Regulating Winding Caused by Ground Fault Initiation on Feeding Cable
Gustavsen, Bjørn Alfred; Portillo, Alvaro; Ronchi, Rodrigo; Mjelve, Asgeir (Journal article; Peer reviewed, 2018)Transformer terminal equivalents obtained via admittance measurements are suitable for simulating high-frequency transient interaction between the transformer and the network. This paper augments the terminal equivalent ... -
