Jean-Jacques Archambault (March 21, 1919 – December 23, 2001) was a Quebec engineer.
Shortly after being hired as a planner at Hydro-Québec he showed interest in the possibility of 735 kV transmission.
With the highest operational voltage elsewhere being 525 kV[1][2] many American specialists affirmed that a 735-kV line was impossible to develop, but the Commission hydroélectrique de Québec approved his idea and launched a project to install a transmission line between Montreal and the Manicouagan-Outardes complex.
[1] The Eastern Canada Council of the Institute of Electrical and Electronics Engineers gives out the Jean-Jacques Archambault Award of Merit in his honour, An amphitheatre in the Hydro-Québec Building in Montreal is also named for him.
In 2005, Hydro-Québec received an IEEE Milestone award for the technology.
