The VSC comprises at least one converter branch (20) comprising at least one module (221-22N), each module comprising a plurality of serially connected sub-modules (241-248) that can be controllably switched to generate a controlled voltage across the module (221-22N) and each module including a first sub-module (241) at one end thereof and a last sub-module (248) at an opposite end thereof. Each sub-module (241-248) includes a first terminal (381), a second terminal (382), an energy storage element (30) and a switching arrangement (32, 34), wherein at least one of the first (381) or second terminals (382) is coupled to a terminal of the energy storage unit (30). A first terminal (381) of the first sub-module (241) of a module (221) at one end of the converter branch (20) is configured to be connected to earth potential on or after shutdown of the converter, and a second terminal (382) of the last sub-module (248) of the module (22N) at the opposite end of the converter branch (20) is configured to be connected to earth potential on or after shutdown of the converter. A grounding arrangement (40) comprising a plurality of switch units (42) is provided, each switch unit (42) associated with one of the plurality of sub-modules (241-248) of each module (221-22N) and configured to connect the first (381) and second (382) terminals of the associated sub-module (241-248) on remote activation of the grounding arrangement (40), following connection to earth potential of the first (241) and last sub-modules (248) of the converter branch (20)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Grounding arrangement for a voltage source converter","description":"A grounding arrangement for a Voltage Source Converter (VSC) in a power transmission system is provided.
