Title: Where And Why Are Isolation Transformers Used - Miracle Electronics
1Isolation transformers are one of the most unique
types of transformers used in the industrial
sector in machineries. These are transformers
that transfer electrical power from a source of
AC power to an equipment or device, while
isolating the powered device from the power
source for safety reasons.
They provide galvanic isolation with no
conductive path present between the source and
load the isolation used to protect against
electric shock, and to suppress electrical noise
in sensitive devices. Applications of isolation
transformers Sensitive equipment Isolation
transformers block the transmission of the DC
component in signals from one circuit to the
other, while allowing AC components in signals
to pass. And, there is special insulation between
the primary and secondary windings, specified to
withstand a high voltage between them. These
characteristics make isolation transformers ideal
for use in sensitive equipment like medical
devices, laboratory instruments, and
computers. Pulse circuits Certain small
isolation transformers are used for isolation in
pulse circuits.
2Electronics testing Isolation transformers are
used in electronics testing equipment to avoid
exposing live metal in a device under test, which
may otherwise prove hazardous because of the
high voltage. When isolation transformers are
used, there is no conductive connection between
the primary and secondary windings, which
results in a very small leakage current flow if
the exposed live metal is connected to the
earth. Equipment at elevated potentials
Isolation transformers are used for the power
supply of devices that are not at ground
potential for example, radio antenna masts.
Without the isolation transformers on such masts,
the lighting circuits would conduct
radio-frequency energy to the ground through the
power supply. Benefits of using isolation
transformers Voltage control Isolation
transformers have their primary and secondary
windings isolated from each other thus reducing
the electrical noise between them. Impedance
matching The low voltage side of a transformer
has low impedance, while the high voltage side
has high impedance. Isolation transformers can
generate superior impedance matching of a
critical load to an electrical circuit. And,
internal low impedance isolation transformers can
create complete isolation from the input AC
line. Other benefits There are many other
benefits that an isolation transformer can
provide, such as continuous filtering of power
line noise, reduction of electrical surges,
removal of neutral-to-ground voltage and noise,
improved reliability, and lowered costs. With
all these benefits, you can have isolation
transformers installed in a variety of different
critical applications, may it be laboratory
equipment, hospital equipment, sensitive
equipment, electronics testing equipment,
diagnostic testing equipment, telecom, and
equipment related to transactions. No matter what
your application, you can get the best quality
