Calculation of Transient Potential Rise on the Wind Turbine Struck by Lightning [PDF]

, 2014
A circuit model is proposed in this paper for calculating the transient potential rise on the wind turbine struck by lightning. The model integrates the blade, sliding contact site, and tower and grounding system of the wind turbine into an equivalent ...

Alleviation of neutral-to-ground potential rise under unbalanced allocation of rooftop pv using distributed energy storage

, 2015
A high penetration of one-phase rooftop solar photovoltaic (PV) units with unbalanced allocation can create considerable neutral current and neutral potential rise in low voltage (LV) four-wire multigrounded distribution networks, even with balanced ...

Above and below-ground bacterial communities shift in seagrass beds with warmer temperatures

Frontiers in Marine Science
Current rates of ocean warming are predicted to exacerbate ongoing declines in seagrass populations. Above-ground responses of seagrass to increasing temperatures have been studied from a direct physiological perspective while indirect effects, including

Hysteretic Characteristics of Wood-Frame Structures Under Seismic Motions [PDF]

, 2009
In order to develop seismic codes that can effectively mitigate damage to wood-frame construction under seismic activity, the dynamic characteristics of wood-frame buildings must be well understood.

An Investigation of Earth Grid Performance Using Graphene-Coated Copper

IEEE Access, 2015
Large power systems are normally operated with their neutral points directly earthed. At a major generating or switching station, this results in the provision of a large earth grid buried in the ground.
