It includes two rectifier stations, Radisson Converter Station near Gillam at and Henday Converter Station near Sundance at , one inverter station, Dorsey Converter Station at Rosser located 26 kilometres (16 mi) north west of Winnipeg at ), and two sets of high-voltage direct current transmission lines. Each HVDC transmission line has two ...
Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open. A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is ...
Schoellkopf Power Station: Niagara Falls, New York United States: Destruction of the plant as it fell from the Niagara Gorge wall and collapsed into the Niagara River, caused by water seeping into the back wall of the power station. One worker was killed and damage was estimated at US$100 million (or $1121 million today, adjusted for inflation).
When line commutated converters are used, the converter station will require between 40% and 60% of its power rating as reactive power. This can be provided by banks of switched capacitors or by synchronous condensers , or if a suitable power generating station is located close to the static inverter plant, the generators in the power station.
At the power station, an electrical generator converts mechanical power into a set of three AC electric currents, one from each coil (or winding) of the generator. The windings are arranged such that the currents are at the same frequency but with the peaks and troughs of their wave forms offset to provide three complementary currents with a ...
