To exploit high wind conditions, wind turbine generator systems are constructed in places with few tall structures; as a consequence, they are often struck by lightning. This results in breakdown and malfunction of electrical, communications, and control systems inside and adjacent to the wind turbine generator system because of ground potential rise. Impulse tests were conducted on an actual wind...
Recently, renewable wind energy is enjoying a booming growth globally to become an important green electricity source to replace fossil fuels. Different from a classical generation plant consisting of synchronous generators, large wind farms are typically made up of many wind turbine generators (WTGs) rated up to several-MWs so far and connected through underground cables in a geographical terrain...
High resistance grounding (HRG) of 480 V to 5 kV industrial power systems increases service continuity, enhances personnel safety and reduces equipment damage when a ground fault occurs. HRG allows maintenance personnel to quickly and safely locate a ground fault while avoiding unscheduled downtime. An abundance of literature has been published on HRG practices since the mid-1970s. Recent years have...
