Summary
[edit]DescriptionSwedens first transformer installed in Bollnäs in 1889.tif |
Svenska: Den svartvita skissen illustrerar en transformator för elektricitetsdistribution i toppen av en trästolpe. Själva transformatorn täcks av ett tak och oktogonformade träväggar. Åtta par trådar går ut radiellt från träväggarna. Denna transformator, uppsatt i Bollnäs år 1889, var den första i Sverige att användas i drift. Endast ett misslyckat försök hade gjort i Stockholm tidigare. Den andra transformatorn i Sverige sattes upp i Motala. |
