Different between power transformer and disturbing transformers

Power transformers and distribution transformers serve different purposes within an electrical power system:

1. Power Transformers:

   Function:

 Primarily used in transmission networks to step up (increase) or step down (decrease) voltage levels. They are crucial for efficient long-distance high-voltage transmission.

 Location: 

Typically found in power generation stations and high-voltage transmission substations.

  Capacity: 

Designed to handle high power levels, often in the range of hundreds of MVA (Mega Volt-Amperes).

  Operation:

 Usually operates at nearly full load for maximum efficiency.

  Size and Cost: 

Larger and more expensive compared to distribution transformers.

 Cooling System:

 Generally have more complex cooling systems due to higher power handling.

2.Distribution Transformers:

  Function:

 Used to step down the voltage to levels suitable for consumer use. They are essential for delivering electricity from the transmission system to individual homes and businesses.

   Location:

 Typically found on utility poles, ground-level pads, or within buildings in residential and commercial areas.

   Capacity: 

Designed for lower power levels, usually ranging from a few kVA (Kilovolt-Amperes) to several MVA.

  Operation:

 Often operate at varying loads, depending on the demand from end users.

Size and Cost:

 Smaller and less expensive than power transformers.

  Cooling System: 

Generally have simpler cooling systems, suitable for lower power handling.

In summary, power transformers are used for high-voltage, high-power transmission over long distances, while distribution transformers are used to provide usable voltage levels to end users.
