Interconnection between countries and surrounding countries provides a large power grid.
With the improvement of wind power technology, increase of wind power capacity, the …

Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) and 15 kV (16.7
Hz) traction systems do not have the characteristics and behaviour of a typical three‐phase …

A new wind turbine transformers protection method against high du/dt switching transients
taking place during a wind turbine operation is described. High-frequency transients …

The energy transition involves integrating numerous pieces of equipment that undergo
frequent switching operations and face the risk of lightning strikes. Consequently, power …

The paper is devoted to the development of a device for protecting facilities with turn-to-turn
insulation, namely transformers and wind generators in order to increase the reliability of …

Due to the extension of the power grid with many complex and compact pieces of power
equipment, transformers will be more exposed to fast transient, resulting from various …

Historically, failures of distribution transformers due to transient overvoltage phenomena
have led to the development of resistor-capacitor snubber circuits for the protection of the …

Novel protection method of wind turbine transformers against high frequency transients
occurring during switchgear operation is described in this paper. Presented results are …

High-frequency switching overvolatges (SOV) are considered as a possible source causing
component failures in existing offshore wind farms (OWFs). In order to study such …

In this paper, modelling and measurement of resonant overvoltages in wind turbine step-up
transformers is presented. A failed 2.7 MVA, 0.690/33 kV step-up transformer with the MV …
