Power Business Unit

The Head Office and Power Transformer manufacturing plant of Wilson Transformer Company are located on a four-hectare site in Glen Waverley, 20 km east of Melbourne’s CBD.

The Glen Waverley plant designs and manufactures generator, substation and auto transformers up to 250 MVA 362 kV, traction (both track-side and on-board locomotive) and other speciality transformers.

Each transformer can be fitted with a conventional relay-based control and monitoring system or alternatively with the Dynamic Ratings DRMCC System.

Electrical design is completed using software ranging from the tender optimization program to sophisticated finite element modelling (FEM) computer programs.
