NF Sternpunktstrom - Low frequency currents in power transformer groundings

Project: Research project

Project Details


Neutral currents in transformer grounding systems arise in HV systems, especially when operated with solid grounded starpoint. The low frequency components can drive a transformer partially in saturation and degrade the operational characteristics. In this project, origin (geomagnetic induced currents GIC) and characteristics of those phenomena will be analysed.
