Power Transformer Types:
Step-up Transformers - A transformer transposes alternating current (AC) from one
voltage to another. Works on a magnetic induction principle that
is designed to either step up or down. A step up transformer
increases the voltage.
- A transformer transposes alternating current (AC) from one
voltage to another. Works on a magnetic induction principle that
is designed to either step up or down. A step-down transformer
decreases the voltage.
- Transformers designed to provide electrical isolation without
stepping voltage and current either up or down are called
- Offers built to order custom transformers such as dry type
transformers, auto transformers, control transformers, and many
Buck Boost Transformers
- The most common use for
buck boost transformers are for boosting 208 volt lines to 230
or 240 volts, and vice-versa. These applications include both
single and three phase lines.
Three Phase Transformers - Three phase
transformers are used to change values of three phase voltage
and current. It is the most common way power is used. Find
out about the different types of three phase transformers.
Single Phase Transformers -
refers to the distribution of electric power using a system in
which all the voltages of the supply vary in unison.
Single-phase distribution is used when loads are mostly lighting
and heating, with few large electric motors.
Low Voltage Transformers -
A Low Voltage Transformer is an electrical device that
transforms 120 volts (line voltage) into 12 volts or 24 volts
(low voltage). Some uses for low voltage transformer are in
Medium Voltage Transformers -
A Medium Voltage Transformer can be connected directly to a
primary distribution circuit and generally has the most load
diversity. These voltage transformers have installation
practices that are generally in accordance with application
recommendations from the Institute of Electrical and Electronic
High Voltage Transformers -
A High Voltage Transformer operates with high voltages.
Typically, these voltage transformers are used in power
transmission applications, where voltages are high enough to
present a safety hazard.
Distribution Transformers -
Distribution transformers are generally used in electrical power
distribution and transmission power. This class of transformer
has the highest power, or volt-ampere ratings. and the highest
continuous voltage rating.
Medical Grade Transformers -
Transformers used in medical devices as well as hospital,
biomedical and patient care equipment are generally referred to
Medical Grade Transformers. Strict safety rules, laws and guides are
used to govern the design and construction of these transformers
Drive Isolation Transformers -
They are used to isolate a drive from a main power line to
prevent the transmission of harmonics that the drives produce
back into the power line. They stop drive harmonics from
disrupting computers and other sensitive equipment.
Toroidal Transformers -
Toroidal Transformers are more efficient than the cheaper
laminated EI types of similar power level. Some of the
advantages are smaller size, lower weight, less mechanical hum,
(making them superior in audio amplifier), low-off-load loss.
Industrial Control Transformers
- Industrial Control Transformers are used to convert the
available supply voltage to the required voltage to supply
industrial control circuits and motor control loads.
Pad Mounted Transformers -
Pad Mounted Transformers are usually single or three phase, and
used where safety is a main concern. They are typically used in
restaurants, commercial buildings, shopping malls and
Pole Mounted Transformers -
Pole mounted transformers are used for distribution in areas
with overhead primary lines. Outside a typical house one can see
one of these devices mounted on the top of an electrical pole.
Dry Type Transformers -
Dry-Type Transformers are available for voltages up through 34.5
kV (although the most common upper limit is 15) and KVA ratings
up through 10,000 (with 5000 as the usual limit). Dry-type
transformers lower the health and environmentally concerns by
using air as a coolant.
Oil Filled Transformers -
Oil Filled transformers are transformers that use insulating oil
as insulating materials which helps cool the transformer. The
oil must remain stable at high temperatures over an extended
periods because it also provides insulation between internal
Auto Transformers -
An Autotransformer is an electrical transformer with only one
winding with at least three electrical connection points called
taps. They are frequently used in power applications to
interconnect systems operating at different voltage classes.
K Factor Transformers -
Some transformers are now being offered with a k-factor rating.
A K-factor rating measures the transformers ability to withstand
the heating effects of non-sinusoidal harmonic currents.
Harmonic Cancellation Transformers
- Harmonic cancellation is performed with harmonic canceling
transformers which are also known as phase-shifting
transformers. A relatively new
power quality product, harmonic canceling transformers are used
for mitigating harmonic problems in electrical distribution
Weatherproof Transformers -
Enclosed transformers come with a weatherproof standard set by

Power Transformer Resources -
In order to operate, electronic circuits all require power.
There are many sources of electrical power but one of the best
is to use a power transformer. A transformer converts an ac
voltage and current to a different voltage and current with
great efficiency. Find more information on power transformers,
the different types available, and a list of manufactures.
