February 2009 - Electrical Engineering

The other day I was talking to a colleague who is a building services consultant.  Despite regularly specifying dry-type/cast resin transformers he was unaware that many manufactures’ use aluminium for the windings; I think Siemens exclusively use aluminium and don’t offer copper anymore.  To confirm this he promptly phoned Schneider Electric and was informed that they use aluminium (or copper on request).

Electrical engineering is a field that covers a wide variety of sub-fields, including electricity and electronics. It is a field that goes back to the early days distributing electrical power. Today, it could cover basic electronics, or more advanced areas, such as control and signal processors, or even the diverse field of telecommunications.
