What Are A Voltage Transformer And A Current Transformer?

What Are A Voltage Transformer And A Current
Transformer?

• Different types of transformers are available in
  the industry. Voltage transformers and current
  transformers are among the two most used
  equipment. The roles of both these transformers
  are different and have their own importance in
  the industry. Lets take a look at what a voltage
  transformer is and then we will explore current
  transformers.

Voltage Transformers

• Voltage transformers are a type of transformer
  that is used to step down and decrease the
  voltage of a system to a safe level. They
  function by letting energy meters monitor the
  operation of electrical connections that may have
  a higher voltage than usual requirements to
  operate efficiently.
• Depending on the use of the application, these
  transformers can be used as low voltage
  transformers or high voltage transformers.
• The role of the voltage transformer includes
  measuring the consumed energy by applications
• It prevents disturbances and faults in the
  electrical systems, thereby protecting the
  expensive machines
• Voltage signals can be used to synchronize,
  events logging, and record events.
• These transformers can isolate the high voltage
  from electricians using the PT
• More importantly, these transformers have the
  quality of converting high voltage into a
  standard secondary voltage of 100V or lower. This
  allows safe and secure use of protective and
  measuring devices.

Current Transformers

• A current transformer is a type of transformer
  that is designed to produce an alternating
  current (AC) in its secondary, which is
  proportional to the AC current in its primary. In
  other words, this machine can step down or reduce
  current levels from thousands of amperes to a
  standard level, either 5 Amps or 1 Amp which
  ensures normal operation. This transformer is
  used when a voltage or current is too high for
  measuring directly.

Primarily, the current transformer is of three
types.

• Wound Type
• This type of current transformer consists of two
  separate windings, primary and secondary. These
  windings are available on a magnetic steel core
  with different turns, depending on the design
• Toroidal (Window) Type
• This type of current transformer comes with no
  primary winding. Instead, it has an opening in
  the core. Through this core, the conductor that
  carries the primary load current is passed.
• Bar Type
• Bar type current transformer utilizes the bus bar
  of the main circuit as the primary winding, which
  is equal to a single turn. It is completely
  insulated from the high operating voltage of the
  system and is generally bolted to the current
  carrying device.

Both voltage transformers and current
transformers play important roles in the
industry. You can choose either of the two
depending on your requirements. Macroplast is an
ISO 90012015 certified Transformer Company in
India that manufactures, designs, and tests
high-quality transformers. The company
manufactures Power Distribution
