Condition assessment of electrical equipment of windfarms is likely one of the most challenging tasks in asset management of power generation. Stresses which come from power electric pulses to harsh environment affects wind turbines electrical components. Additionally wind turbines are expensive and critical components, due long times required to inspect, replace or restore after failure in particular in off-shore installations.
The reliability of electrical systems in the presence of frequency converters may be reduced significantly by the occurrence of Partial Discharges (PD) and voltage/current transients, which can affect the insulation of the electrical equipment installed. Impulse voltage supply gives rise to over-voltages and uneven potential distributions which stress dramatically electrical insulation. It has been demonstrated experimentally that ageing under high-frequency impulse waveforms is accelerated significantly with respect to sinusoidal waveforms.
