Transformers are often combined
with phase converters to build an electrical system that delivers
proper power to three-phase equipment. While transformers have many
properties, their basic application is in changing the voltage of
electrical power. Some of the more common types are
buck-boost transformers and
service in North America is nominal 208 volts, while single-phase
service is nominal 240 volts. So, if you are using a phase converter to produce
three-phase power, the three-phase voltage is likely to be 240. Many motors and
electrical equipment are designed to operate on either 208 or 240
for some, 240V may be too high to safely operate. A transformer
offers a cost effective, reliable method of adjusting voltage to the
been widely used for over 100 years and are manufactured by many
companies. There is usually nothing proprietary about their
design and performance, so a customer has many choices when it is
time to buy a transformer.
Just make sure the manufacturer is reputable company experienced in
transformer design and production, then choose a supplier with
competitive prices and good service.
The characteristics of the
operated equipment can be important in choosing the correct
transformer, so make sure the supplier has qualified technicians
that understand your application.
