Product Description

Types of Distribution Transformer
Based on the application or requirement, these transformers are categorized into different types like single phase, three phases, underground, pad-mounted, pole-mounted transformers.

The uses of the distribution transformer include the following.

This transformer changes from high voltage electricity to low voltage electricity, used in homes & businesses.
The main function of this is to step down the voltage to provide isolation between two windings like primary & secondary
This transformer distributes the power to remote areas which are generated from the power plants
Generally, this transformer distributes the electrical energy to industries with less voltage under 33KV and 440volts to 220volts for domestic purposes.

FAQs
Which transformer is used in an electrical distribution system?

A step-down transformer is used in an electrical distribution system

2). What is the difference between distribution & power transformer?

The power transformer is used in transmission networks with high voltages whereas a distribution transformer is used in low voltage distribution networks.

3). What are the types of transformers?

The different types of transformers are step up, step down, power, distribution, instrument, potential, comprising current, single-phase, 3-phase, auto, etc.

4). Why transformers are rated in kVA?

Because they do not change the power factor (PF) of their output power.

5). What is the formula for kW to kVA?

Apparent power (kVA) = Actual power (kW) / power factor (pf)

Thus, this is all about an overview of the distribution transformer. It is used to distribute the electrical energy in industries with a voltage less than & 440v to 220v for domestic purposes. It works with less efficiency and they are small in size, easy to install, include low magnetic losses.


What is a Distribution Transformer?
Unlike a power transformer, distribution transformers serve for circulation purposes. Such equipment will, therefore, bring down (step down) the voltage and incidental level of a power transmission line to a predetermined scale. This predefined level is also referred to as the end-user safety level, either for domestic consumers or for industrial purposes.

Though similar in stature to a power transformer, a distribution transformer's voltage range varies between 33kV to 430V.


Single-phase indoor high-voltage transformer is a kind of power transformer which is mainly used in the high-voltage side of single-phase power system. Here are some information about the technical parameters and applications of single-phase indoor high-voltage transformers:

Technical Parameters:

GGAj02 series single-phase full-wave high-voltage silicon rectifier transformer: this transformer has two impedance forms for users to choose, medium resistance and high resistance. Medium resistance rectifier transformer combines the advantages of domestic high and low resistance rectifier transformer, suitable for the electric field working conditions of poor and large load changes; high resistance transformer design circuit total resistance of 35-40%, the use of the main circuit total resistance of the integral characteristics of the rectified output voltage waveform coefficient, in order to get a lower peak-to-average value ratio of
.
DC-50KVA/27.5KV/0.23KV single-phase dry-type transformer: design life of more than 30 years, impedance voltage of 6.5%, the use of energy-saving transformers, in line with national energy-saving related regulations
...
Fully self-protected single-phase column-mounted transformer: product models include DH15-M or D11-M, rated voltage of 10kV/(0.22~0.24)kV or 2×(0.22~0.24)kV (or voltage proposed by the user), with tapping ranges of ±5%; ±2×2.5%, frequency of 50Hz, and coupling group labeling of II0 or II6, applicable to outdoor environment.

Applications:

Single-phase distribution transformer installation location selection: the installation location of single-phase distribution transformer is less restricted by geographical factors, and more constrained by the load nature factors. In the three-phase distribution transformer power supply radius is too large, the load is too heavy or there is no three-phase electricity users, the installation of single-phase distribution transformer can solve the problem of low voltage, capacity increase, reduce losses, and save investment.
Application Example: In Suqian City, the installation of single-phase distribution transformer can solve the problem of low voltage and capacity increase and save investment.

Application examples: in Suqian city, the widespread installation of single-phase distribution transformers has brought significant social and economic benefits. For example, a 4 houses 16 units of 160 residents of the city south resettlement district, by 1 S7-315/10 three-phase distribution transformer power supply, changed to 8 sets of 50kVA suspended single-phase distribution transformer power supply, the average low-voltage power supply radius from 280m reduced to 12m, significantly improving the voltage qualification rate and the user power supply reliability rate.
The average low voltage power supply radius was reduced from 280m to 12m, which significantly improved the voltage compliance rate and the reliability of power supply to users.
This information provides some basic technical parameters and application scenarios of single-phase indoor high-voltage transformers, which helps to understand their role and advantages in the power system.
