Each of them had a weight of 10,200 kg (22,500 lb), a length of 4.57 metres (15.0 feet), a width of 2.44 metres (8.0 feet) and a height of 3.96 metres (13.0 feet). Between 1992 and 1993 the mercury arc valves of Pole 1 were replaced with solid state thyristors from GEC Alsthom, increasing the maximum power and voltage of the line to its current ...
The Eel River Converter Station consists of two separate 12-pulse bidirectional solid-state non-synchronous HVDC ties of 4800 thyristors [2] (each nominally rated 160 MW) connecting 230-kV transmission systems of Hydro-Québec and NB Power. The converter station has a nominal throughput rating of 40 MW to 320 MW and an overload capability of up ...
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse.
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

McNeill HVDC back-to-back station is the most northerly of a series of HVDC interconnectors between the unsynchronised eastern and western AC systems of the United States and Canada. The station, which was built by GEC-Alstom, can transfer a maximum power of 150 MW at a DC voltage of 42 kV. The station is unusual in many respects and contained ...
450kV HVDC line (at right), on south side of Autoroute 20 east of the Nicolet station near Sainte-Eulalie, Quebec.. The Quebec – New England Transmission (officially known in Quebec as the Réseau multiterminal à courant continu (RMCC) [1] and also known as Phase I / Phase II [2] and the Radisson - Nicolet - Des Cantons circuit, [3] and known in New England as the Northern Pass) is a long ...

A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current of one frequency to alternating current of another frequency. The device may also change the voltage , but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much ...
