Transformer Inrush Measurements in a Distribution Grid Laboratory

<p>This data set contains measurement data of distribution transformer inrush transients obtained in the Distribution Grid Laboratory at the IAEW at RWTH Aachen University. Within the framework of the investigations, a medium voltage feeder with one or multiple medium/low voltage transformers is energised. The setup is either supplied by the public medium voltage grid or by a grid-forming converter. In the latter case, grid voltage distortions can be observed during the inrush transient due to output current limitation of the converter.</p> <p>The inrush measurements were carried out within the framework of the project DiSCo (Distribution System Inrush From Grid-Forming Converters). The authors gratefully acknowledge funding by E.ON SE as well as the technical support in development, execution and analysis of the experimental investigations by Westnetz GmbH. In addition, we would like to thank the colleagues of the Institute for Power Generation and Storage Systems (PGS) for their support and the informative discussions.</p>
