of Power Transformers. Access to wholesale pricing!
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!
Jefferson Transformers
In business over 93 years; supplying a
diverse selection of products to an equally diverse clientele. |
PURPOSE AND APPLICATIONS
OF POWER TRANSFORMERS
Power Transformers
are used for a variety of reasons,
but they all have one thing in common; namely that the power being received
must be tailored for the specific use.
 One of the main applications for
Power Transformers is to convert the power being transmitted to a
very high voltage as it is much more efficient to transmit power at
exceedingly higher
voltages. In this way less power is lost due to resistance. Step Up
Transformers and 3
Phase Transformers are used at this stage.
Once the power reaches a region, area or facility where
power is to be used, a Power Transformer or series of Power Transformers
must bring the received power to a specific range that will fit the local
needs.
The Power
Transformers would
specifically include
Buck Boost Transformers (which adjust to
low voltage applications, motor applications and adjustments to chronic high
or low voltage conditions), Step Up Transformers (to raise any consistently
low voltage condition as in lines that repeatedly test out at only 108 volts
where 120 is desired), and Step Down transformers (where the voltage is
being reduced from a chronically high voltage condition).
Often, once
the power is channeled through the line, it can acquire unwanted
characteristics. Due to fluctuations in available power, increased or
decreased usage at certain times of the day, and other factors, the voltage
may be intermittently a bit higher or lower than optimum or voltage may be
right but there may be instances of feedback, sudden spikes or drops,
induced currents or ghost currents, harmonic currents and instances of
static charges that could affect sensitive equipment or even bleed into
people exposed to that equipment.
These are mainly addressed through the use of
a variety of Power transformer types; AC Line
Reactors (designed to handle harmonics, surges, fleeting currents and
anything that affects optimum performance of motors and electronics),
Isolation Transformers (which can include shielding so as to eliminate local
induced currents and static charges by draining them off to ground before
the current reaches the final stage) and
Medical Isolation Transformers
(which specifically bring all equipment within closely regulated legal and
safety tolerances designed to protect electronics, personnel and patients
exposed to the equipment.)
Some Power Transformers apply to
converting the power from one phase type to another. A major transmission
line is usually 3 phase and, as mentioned above, a 3 phase Transformer will
be used at the power end and sends the power on three individual lines which
will have to be converted later at the receiving or "load" end.
It is
important to make the distinction between transformers and converters as
they are very different in application. An incoming line to a facility is
usually single phase. 3 Phase Converters are employed here to supply power
to 3 phase equipment.
(See special comparison notes on
Static Phase
Converters.)
The variety
of uses of power can demand the need for a very
specific application and custom Power Transformers can be ordered for these
occasions.
