With an increasing requirement to lower the costs of delivered renewable energy, the
maintenance costs for marine renewable energy (MRE), due to accessibility issues, are an …

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

This paper reports on a comprehensive study on a measurement method for the impedance
characteristics in the frequency domain of magnetic rings as a function of DC-bias current up …

In offshore wind farms, reignition overvoltages are usually caused by switching-off
operations of vacuum circuit breakers, which degrade the insulation of power equipment …

It is crucial to protect offshore wind farms from overvoltages because of bad accessibility and
high maintenance costs. During the process of switching-off a shunt reactor with a 40.5 kV …

Despite having several modern transformer protection schemes, the protection engineer
prefers the universally adopted unit‐type differential protection scheme for the current …

The multiple reignitions of vacuum circuit braker (VCB) while switching off the shunt reactor
in an offshore wind farm (OWF) would produce a high overvoltage. The post‐arc process of …

The high amplitude and steep overvoltage generated by the breaking of the vacuum circuit
breaker in the wind farm damages the inter-turn insulation of the transformer. There is a …

Magnetic materials in the form of magnetic rings are widely used in power engineering
products. In many cases, they operate in high frequency and in nonlinear conditions, eg, as …

Magnetic rings are extensively used in power products where they often operate in high
frequency and high current conditions, such as for mitigation of excessive voltages in high …
