Abstract In response to the problem of transformers blowing up or even burning together with detuning devices in recent years, an assessment method based on equivalent transformer winding currents is proposed for potential (Potential Transformer, PT) low and medium voltage distribution networks. Firstly, damage mechanism analyzed thermal breakdown identified as main cause insulation. At same ti...

This paper considers the history of oscillating water column (OWC) systems from whistling buoys to grid-connected power generation systems. The power conversion from the wave resource through to electricity via pneumatic and shaft power is discussed in general terms and with specific reference to Voith Hydro Wavegen’s land installed marine energy transformer (LIMPET) plant on the Scottish islan...

Based on the linear wave theory, the mild-slope equation (MSE) is a preferable mathematical model to simulate the wave propagation nearshore. On the basis of developed self-adaptive finite element model, an interative method is used to determine the wave direction angle to the boundary and to improve the treatment of the boundary conditions. Thus a numerical model to solve MSE is developed in t...
