Basics of distribution and power transformer

Basics of distribution and Power transformer!

Definition of Distribution transformer?

For transferring the electrical energy from a primary distribution to a secondary distribution circuit or a user circuit is the purpose of a distribution transformer.

They are referred for the purpose of electric power distribution electric power distribution and are also termed as step down transformers. There are various types of transformer used in the distribution system like single phase transformer, three phase transformer, pad mounted transformer, pole mounted transformer, and underground transformer. They are basically compact devices and filled with insulating oil. There are various sizes and efficiencies available in the market. Depending on the purpose and budget the distribution transformers are chosen from the user end.

Distribution transformer and its special need?

Since it is energized for 24 hrs even without load; there is a low iron loss as a distribution transformer.

As the distribution transformer is working at full load; the maximum efficiency is very low at load.

For availing minimum voltage regulation the leakage reactance is kept low and hence a higher efficiency is achieved. Top changers do not have any such provisions.

Definition of Power transformer?

For transferring electrical energy in any parts of the electrical circuit between generator and primary distribution circuit. The distinction between power and distribution transformers must not be as per KVA rating according to IEEE standards It is composed of a coil wrapped around an electromagnet which transfers the electricity. They operate at 100% efficiency unlike distribution transformer. One more difference between power and distribution transformers is that power transformers is for handling high voltages and distribution transfer is for dealing with the low ones. Distribution transformers are fed with power from the Power transformers thereby providing small amounts of power to each and every home.

What Does a Power Transformer Do? Electrical induction is the process of transforming the current from a power transformer along with electric voltage running into a current and voltage that is used for a specific system. Running is backed up by it. The frequency of the electricity remains the same but transformed at a different value for both the voltage and current. Along with distribution transformer power works together for regulating power in transmission networks by decreasing or increasing the voltage levels relying on the requirement of the consumer.

Power transformer and its special requirements It has cooling and a higher insulation.

Voltage regulation and tap changer to cope up with.

Higher mechanical and electrodynamic stress needs to be maintained.

Applications of Power transformer Various kinds of electronic circuits use this transformer.

Transmission and distribution of electric power are used in these transformers widely in power plants, traditional electric utility companies, etc.
