𝗗𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗶𝗼𝗻 𝗧𝗿𝗮𝗻𝘀𝗳𝗼𝗿𝗺𝗲𝗿 | Parts of Transformer 

A type of transformer used to step down the voltage from higher transmission levels (typically in the range of 11 kV to 33 kV) to lower voltages (typically 230/400 V) suitable for use in homes, industries & other end-user applications. The primary function of a distribution transformer is to ensure that electrical energy reaches consumers at usable voltage levels.

𝗠𝗮𝗶𝗻 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀 𝗼𝗳 𝗮 𝗗𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗶𝗼𝗻 𝗧𝗿𝗮𝗻𝘀𝗳𝗼𝗿𝗺𝗲𝗿:

💢𝗖𝗼𝗿𝗲: Main Component & helps in reducing energy loss due to eddy currents and hysteresis.

💢𝗪𝗶𝗻𝗱𝗶𝗻𝗴𝘀:

𝗣𝗿𝗶𝗺𝗮𝗿𝘆 𝗪𝗶𝗻𝗱𝗶𝗻𝗴 (𝗛𝗧):Receives High Voltage input from transmission lines.

𝗦𝗲𝗰𝗼𝗻𝗱𝗮𝗿𝘆 𝗪𝗶𝗻𝗱𝗶𝗻𝗴 (𝗟𝗧): Delivers the reduced voltage to the load side.

Windings are typically made of Copper or Aluminum & their choice depends on cost and performance considerations.

💢𝗜𝗻𝘀𝘂𝗹𝗮𝘁𝗶𝗼𝗻: Windings & Core are insulated to prevent Short Circuits and Breakdowns. (Oil & Insulating Papers)

💢𝗧𝗮𝗽-𝗖𝗵𝗮𝗻𝗴𝗲𝗿: Transformers have a tap changer to adjust the output voltage (+2.5%, Principle, -2.5%, -5%, -7.5% Taps)

💢𝗕𝘂𝘀𝗵𝗶𝗻𝗴𝘀 (𝗟𝗧 &𝗛𝗧): Insulating Devices that allow the electrical conductors to pass through the tank of hashtag

#Transformer while maintaining the electrical insulation.

💢𝗧𝗮𝗻𝗸: Transformer is housed in a tank that contains the insulating oil (in oil-type transformers) or air (in dry-type transformers). The tank provides mechanical protection and also helps dissipate heat.

Cooling System: In oil-filled transformers, oil serves both as an insulating and cooling medium and Fins/ Headers/ Tubes used to increase the heat dissipation.
