3 Phase Transformers
Used to set voltages in all 3 phase
applications where a 3 phase power supply exists.
3 Phase Converters
Convert single phase to 3 phase power when 3 phase is most desirable.
Medical Isolation Transformers
Necessary for any hospital and medical
equipment covered by state and federal safety and performance regulations.
Isolation Transformers
Separates the incoming power from that
which finally runs the equipment. Protects against unwanted characteristics
generated in the use of power within an area.
Buck Boost Transformers
Often used for low voltage applications
and raising voltage for 230V motors or 120V lighting systems;
designed to reduce (buck) or
raise (boost) line voltage from 5% to 20%.
Custom Transformers
Specific needs can be filled by custom
building a transformer to the requirements of the customer.
Step Down Transformers
Adjust voltage from high voltage
transmission lines or to correct local lines for chronically high voltage
conditions.
Step Up Transformers
Adjust voltage for transmission at higher
voltages or to correct local lines for chronically low voltages.
AC Line Reactors
Adjust, block or otherwise handle
unwanted power characteristics often generated during normal use of power in
an area.
Acme Transformers
A reliable leading American transformer
distributing company.
Hammond Transformers
Originated as a family -owned and run
company and is now a nation-wide distributor!

PURPOSE AND APPLICATIONS
OF STEP DOWN TRANSFORMERS
Step Down Transformers
reduce the voltage to the fit the next level of desired use. It usually
comes in extremely high voltages of about 69 kV to 765 kV or above in the
main transmission lines to 33kV and 66kV in sub transmission lines. In local
substations having Step Down Transformers it is lowered again to
voltages of around 2.4 to 34.5 kV and distributed into neighborhoods where
it is further lowered via other Step Down Transformers on power poles
to match home or business voltages up to 400V. Perhaps it will go to some
point in a factory, shop, home or even the much smaller applications and be
reduced again to fit a lower voltage piece of equipment.
Step Down Transformers
have a primary winding of higher number of turns than the secondary winding.
The AC power is lowered in a specific ratio of higher to lower number of
windings that will result in the final voltage desired. There are no
connections between the two windings, but the current is transferred by
induction. The secondary winding is typically of larger gauge wire since it
carries a higher current than the primary. The higher current is a function
of a fixed mathematical ratio between the number of primary vs. secondary
windings. Since power is fixed, lowered voltage results in increased
amperage; the lowering of voltage is inversely proportional and results in
increase of amperage.
Step Down Transformers are
relatively simple in design but must have the exact ratio of windings in
each circuit so as to deliver the appropriate current and voltage; otherwise
damage may be done to equipment connected to the supply. For this reason
both incoming and outgoing voltages must be known prior to selecting any
Step Down Transformer. In fact, at times it may be necessary to order a
Custom
Transformer for a particular application as that power source or that
application may not conform to conventional designs.
Step Down Transformers
and, indeed, any other kind of transformer can be, and are made using
aluminum, copper and sometimes other metal windings. Copper costs more
initially, but it lasts longer, carries more current with a smaller diameter
wire, and heats up less than aluminum. Application, budget and other factors
must be considered before installing a particular transformer.
