These Transformers are used to supply variable speed drives (VSD)
for motor control. A VSD typically injests a whole spectrum of
harmonics into the supply lines, and the transformers design needs
to accommodate these harmonics. A convertor transformer is
typically rated at **0% capacity, when a Distribution transformer
is typically rated at *0% capacity. VSD drives are based on power
electronic and usually require a neutral line, hence the most
common vector group is DYn*1, i.e. a Delta Primary with a star
Secondary with the neutral point brought out.
FURNACE TRANSFORMERS
The smeltering Industry uses AC & DC processes depending on the
Arc Furnace application. DC Electric Arc Furnace (EAF) Transformers
are similar in design to rectifier transformers, but have many more
taps and on-load tap-changers. AC (EAF) transformers are subjected
repeat short circuit conditions that require a more conservative
design. They too have many taps and on-load tap changers. The AC
(EAF) Transformers are generally manufactured as single phase units
which allow the furnace design and process to be optimised.
