What Qualities Make a Medical Grade Transformer?
- Miracle Electronics Medical grade These
words describe safety and precaution. Thus, when
medical grade transformers are required, it is
important that the transformers are highly safe.
Although transformers in itself are safe, so as
to provide safe amount of power to the end
devices, you can imagine the highest level of
safety imbibed into medical grade transformers!
This is the main difference between a medical
grade transformer and a standard transformer.
Transformers that are considered to be medical
grade, need to satisfy a number of additional
safety rules and guidelines, beyond those
required for non-medical grade transformers. They
are thus designed in a way to protect patients,
medical equipment, and caregivers by maintaining
strict adherence to a lot many aspects. Some of
the guidelines that medical grade transformers
abide by include maximum temperature rise,
minimum creepage distance,

minimum air clearance, maximums on earth or
enclosure leakage current, and compliance to the
harmonized IEC 60601 standard. Types of medical
grade transformers There are two main types of
medical grade transformers available safety
ground transformers and reinforced insulation
transformers. Heres a short description about
the two. Safety ground transformers These
transformers utilize standard transformer
isolation, with a safety shield between the
primary and secondary coils, and insulation
between the shield and each coil, maintaining
leakage current maximums. If this isolation
fails, the AC input current is immediately
redirected to the ground through the shield,
which should trip the over-current
device. Reinforced insulation transformers
Also known as double insulation transformers,
these are larger than standard transformers,
having two or more means of insulation thus the
name. with such double insulation, the added
advantage is that if one insulation layer fails,
then the other will cover up for it, and
maintain isolation. Benefits of medical grade
transformers With the increased safety standards
and guidelines that medical grade transformers
abide by, medical grade transformers certainly
bring much more benefits than a standard
transformer. Some of the

• advantages that medical grade transformers bring
  with them include
• Compact size and reduced weight
• Low power losses
• Built-in thermal protection
• Low leakage current design
• Reduced safety testing time, thus allowing faster
  to-market time
• Compliance with internationally recognized safety
  agency standards
• Applications of medical grade transformers
• Medical grade transformers are used in a variety
  of applications like MRI equipment, imaging
  equipment, medical system trailers, PET
  equipment, and CT equipment. They can be used in
  components like inductors, reactors, and chokes.
• However, this does not mean that only medical
  grade transformers are used in medical
  applications. Many other kinds of transformers
  can be used for many applications, some of them
  being water-cooled transformers, dry-type
  transformers, isolation transformers (), and
  auto transformers. Depending upon your
  application and requirements, the right kind of
  transformer can be chosen for you. But for this,
  you need a genuine transformer manufacturer to
  help advise you to make the right choice, and
  also design one for you. Miracle Electronics is
  one such medical transformer manufacturer in
  India you can approach.
