Transformers typically use two or more coils of wire, called "windings," to transfer energy from one circuit to another. The windings are wrapped around a common iron core where the primary and secondary windings are connected to the power source and the load, respectively.
As the alternating current in the primary winding changes direction, it creates a changing magnetic field. This magnetic field produces the necessary energy for the secondary winding. The transformer's job is to transfer energy from the primary circuit to the secondary circuit with as little loss as possible.
The main purpose of a power transformer is to convert high-voltage electricity into lesser and more manageable electric sources for both commercial and residential use. A transformer lowers the voltage rate from the power grid to a safer and more manageable level where the secondary winding can use this converted electricity to power businesses and homes.
The load might be a light bulb, a motor, or some other type of equipment. The transformer converts and maintains the proper voltage to ensure continuous use without potentially damaging the appliance.
The transformer can also increase the voltage if the load requires more juice than the current power available from the power grid. This is often the case with equipment that uses a lot of electricity, such as electric furnaces and large air conditioners.
In addition, power transformers can be used to change the voltage from one level to another. This is often done to transmit electricity over long distances.
Power transformer manufacturers hone their craft by designing transformers that minimize energy loss while providing the necessary voltage conversion.

Both terms are commonly used interchangeably, but there is a technical difference between the two types of transformers. The clear difference between a power transformer and a distribution transformer is that the former is used during the load period while the latter operates in both load and no-load periods.
Distribution transformers are meant to step down the voltage from the power grid to a safe level for both commercial and residential applications.
In addition, distribution transformers are usually smaller in size than power transformers. This is because distribution transformers typically have a lower capacity than power transformers.

There are ten power transformers types:
Step-up power transformers
Step-down power transformers
Three-phase power transformers
Single-phase power transformers
Distribution power transformers
Instrument power transformers
Indoor power transformers
Outdoor power transformers
Oil-type power transformers
Dry-type power transformers
A step-up transformer is used to convert low-voltage (LV) and high-current (HC) electricity into high-voltage (HV) and low-current (LC) electricity. It transfers the power transformer's high-current, low-voltage primary side to the low-current, high-voltage value secondary side.
Step-up transformers increase the primary voltage to secondary voltage. As a result, the step-up power transformer's secondary winding will have more turns. This increases the transformers' capability to transfer energy and power.
Step-down transformers are the exact opposite of step-up transformers. It transforms high-voltage (HV) and low-current (LC) electricity into low-voltage (LV) and high-current (HC) electricity.
Simply put, step-down power transformers do the exact opposite of a step-up power transformer. Power transformers in substations have the ability to both increase and decrease voltages. However, its capacity will depend entirely on the purpose and situation.
The step-down transformer also has a secondary winding that has fewer turns than the primary winding. This results in the transformer having a lower capacity to transfer energy and power.

A three-phase transformer is a type of power transformer that's commonly used for projects that features a compatible three-phase power system. It's a more efficient way to transmit electricity compared to a single-phase power system.
Three-phase systems are often used in industrial and commercial settings where large amounts of electricity are needed. This is because three-phase systems can transmit more power than single-phase ones while using less conductor material.
One of the benefits of using a three-phase system is that it can provide a steadier and more constant flow of power. This is due to the fact that three-phase systems have three alternating currents that are offset by one-third of a cycle. This offset minimizes any gaps in the power supply, which results in a steadier flow of power.

A single-phase transformer uses a single-phase alternating current. So it's heavily dependent on an operational voltage cycle that's generated by a single alternating current in a unified time phase.
Single-phase systems are often used in residential settings where lower amounts of electricity are needed. The primary to the secondary windings' electric ratio will determine the transformation the single-phase transformer can provide.
Daelim's single transformer has two types: single phase pole transformer mounted and single phase pad mounted transformer. A large number of exported to North America and Central and South America, mainly for power distribution in residential areas.

A distribution transformer decreases the voltage of an electric power distribution system to the level that's compatible with the voltages that the customer uses. Various power transformer manufacturers typically use it for commercial or domestic purposes.
A distribution transformer usually has excellent voltage regulation levels that maintain a steadier voltage. This is because it typically features a tap changer that can automatically adjust the turn ratio of the transformer's primary and secondary windings.
This feature results in the distribution transformer having the ability to maintain a steadier voltage even when there are load changes. The tap changer is usually located on the secondary side of the distribution transformer.

An instrument transformer is a type of power transformer that's used to isolate and change certain attributes of an electric circuit. These attributes can include voltage, current, or impedance. Instrument transformers are often used in industrial settings where electricity is measured or monitored.
One of the benefits of using an instrument transformer is that it decreases high currents and voltages to mitigate the values to a safer level. This is done by using either a current transformer or a voltage transformer.
A current transformer changes the high primary current into a lower secondary current. This is done by wrapping the primary conductor around a magnetic core and passing the resulting current through the secondary winding.
A voltage instrument power transformer converts the high-voltage primary side into low-voltage secondary side. This is done by placing the primary and secondary windings on different cores and passing the current through the primary winding. The newly converted voltage will then travel from the primary winding and through the secondary winding.
An indoor transformer is a type of power transformer that's installed indoors. Indoor transformers are typically used in settings where there's a lower risk of fire or explosion. This is because indoor transformers are less likely to be damaged by weather conditions.
Indoor transformers are also often used in settings where aesthetics are important. This is because indoor transformers can be hidden from view more easily than outdoor transformers.
An outdoor transformer is a type of power transformer that's installed outdoors. Outdoor transformers are typically used in settings where there's a higher risk of fire or explosion. In addition, outdoor transformers are more likely to be damaged by weather conditions.
Outdoor transformers are also often used in settings where space is limited. This is because outdoor transformers take up less space than indoor transformers.
As the name suggests, an oil-type transformer is a type of power transformer that uses oil (transformer or mineral oils) as a coolant. Oil-type transformers are often used in settings where there's a need for a high degree of protection. This is because oil-type transformers are less likely to catch fire than air-cooled transformers.
Get it now: How much do you know about oil-immersed distribution transformers?
