Five small variable-frequency [[electrical transformer|transformer]]s with a total power rate of 25 MVAMW were in use at [[Neuhof Substation]], Bad Sachsa, Germany for coupling power grids of former East and [[West Germany]] between 1985 and 1990.

Langlois Substation in [[Québec]], [[Canada]] ({{Coord|45|17|13.76|N|74|0|56.07|W|}}) installed a 100 MW variable-frequency transformer in 2004 to connect the asynchronous grids in Québec and the [[northeastern United States]]. This was the first large scale, commercial variable frequency transformer, and was installed at [[Hydro-Québec]] Langlois substation and is located electrically near sixteen hydro generators at [[Les Cèdres, Quebec]] and thirty-six more hydro generators at [[Beauharnois,_Quebec]]. The operating experience since April 2004 has demonstrated the VFT’s inherent compatibility with the nearby generators<ref> Marchen, P.E, Marczewski, J.J, D'Aquila, R, Hassink, P., Roedel, J.H. and Bodo, R.L.
