Distribution Transformer in Lucknow UP

A Distribution Transformer is a type of electrical transformer that is used to step down the high voltage from power transmission lines to a lower voltage level suitable for use by residential, commercial, or industrial consumers.

Definition:

A distribution transformer transfers electrical energy from the primary distribution circuit (typically 11 kV or 33 kV) to the secondary distribution circuit (usually 400V/230V), making it safe for end-user consumption.

Key Features:

• Low rating: Typically ranges from 25 kVA to 2500 kVA.
  
• Step-down transformer: Reduces high transmission voltage to usable levels.
  
• Mounted on poles (pole-mounted) or on the ground (pad-mounted).
  
• Operates 24/7 to supply continuous power.
  

Applications:

• Powering homes, schools, hospitals, shops, and small factories.
  
• Final voltage transformation in the power distribution system.
  
• Used in both urban and rural areas.
  

Types:

1. Pole-mounted transformers (common in rural areas).
   
2. Pad-mounted transformers (enclosed and ground-based, used in urban areas).
   
3. Underground transformers (used in underground distribution systems).
   

Construction Components:

• Core: Made of laminated silicon steel.
  
• Windings: Copper or aluminum conductors.
  
• Insulation: Oil or dry-type.
  
• Tank: Contains transformer oil for cooling and insulation (in oil-cooled types).
  
• Bushing terminals: For connecting input and output lines.
  

Cooling Types:

• Oil-cooled (most common).
  
• Air-cooled (dry-type, used indoors).
  

Advantages:

• Reduces voltage to safe levels for end users.
  
• Improves energy efficiency in power delivery.
  
• Reliable and requires low maintenance.
