Welcome To Royal Transformers

• Royal Electricals was in progress in 1987 as a
  company firm, based in Vithal Udhyognagar, Anand,
  a Milk City, and well linked by Rail and Road. We
  are famous transformer manufacturers providing
  filter equipment on rental basis as per agreed
  terms and conditions. We are employ most
  complicated tools and machineries to achieve
  desired excellence in our end item for
  consumption.

When And Why Are Distribution Transformers Used?

• The crucial role of transformers in the
  electrical industry is well known to everyone.
  But, most of the people get confused when it
  comes to the types of transformers. The types
  differ according to the requirements. From
  step-up, step-down transformers to power and
  distribution transformers, each has their own
  specialty and use. This article presents the
  significance of distribution transformers in the
  industry. For those, who are not sure about the
  distribution transformers, this can be a great
  help. Distribution transformers in India are high
  on quality and are in accordance with the demands
  of present times.

What are distribution transformers?

• Distribution transformers are known to step down
  the voltage used in the distribution lines to the
  level used by the customer. Thus, they provide
  the final voltage transformation in the electric
  power distribution system. Their ratings are
  normally less than 200kVA. They are energized
  throughout the day. Their design, therefore, has
  an important role in reducing iron losses.
  According to their design, they hold maximum
  efficiency at lower loads. If there is a need to
  have better efficiency, the voltage regulation
  should be kept to a minimum. Another term used
  for them is service transformers.

Classification

• The classification of Furnace transformers India
  as distributed transformers includes various
  sub-classifications. Following are the
  classifications of Distribution transformers in
  India and other countries based on certain
  factors.

5

• Pole, pad, underground vault transformers form a
  category depending on the mounting location.
• According to the type of insulation, there can be
  liquid-immersed or dry-type distribution
  transformers.
• Depending on the number of phases, the
  transformers can be single phase or three phase
  ones.
• Voltage class and Basic Impulse Insulation Level
  also form different categories of distribution
  transformers.

When and where are the distribution transformers
used?

• Distribution transformers are used for the power
  supply facilities through a utility pole or
  underground power lines to the premises of the
  customer. Settlements such as isolated houses,
  farmyards etc. also take the benefit of the power
  supply using distribution transformers.
  Distribution transformers in India are also used
  on a large scale to provide the power supply even
  to the farthest places.

• Railways also make good use of Transformers oil
  filtration services in the power supply of the
  overhead wire electrified with AC. The number of
  customers in an area is the deciding factor for a
  number of customers fed by a single distribution
  transformer. A single distribution transformer
  might be enough to feed several homes in an urban
  area whereas rural areas may require one
  transformer per customer. Similarly, a large
  commercial complex will require more than one
  transformer.

• The power collector networks of wind farms also
  use distribution transformers for stepping up the
  power from each wind turbine to connect to a
  substation several miles away.

Distribution transformers and power transformers

• Although both of them fall into the category of
  transformers, they remain different in a lot of
  ways. The main difference lies in their voltages.
  The transmission network of higher voltages like
  400 kV, 200 kV etc. makes use of power
  transformers. The general rating is above 200
  MVA. Whereas, distribution transformers fulfill
  the purpose of lower voltage distribution
  networks like 11 kV, 3.3 kV,440V etc. They are
  there to provide the end-user connectivity and
  have rating usually lower than 200MVA. Thus,
  whenever it comes to the power supply to end
  user, it is understood that distribution
  transformers are working behind the scenes.

• The sole purpose of using Distribution
  transformers in India is for distributed power
  supply along with certain other operations. The
  technology innovations play a great role in
  enhancing the power supply services. This all
  helps in growth of the country thus helping in
  one of the biggest missions.
