Distribution Transformers are used on distribution side not transmission side.
Core losses or Iron losses ( Hysteresis and eddy current losses ) are proportional to the square of the voltage.
Copper losses are proportional to the square of the current.
Distribution side voltage is less compared to the transmission side.
core losses are constant irrespective of the load, but copper losses varies with the load.
Transmission side transformers are not usually stopped from working by the operator frequently, they continued to work throughout the year until and unless if there is a problem and also they almost have constant load. So they are going to have more core losses. So their core is designed in order to get less core losses. Any way the copper losses will be less since the current is less because voltage is more.
Distribution side transformers are having more load fluctuations and more stoppages.Their voltage is low so they will have less core losses, no need to design a better core, but distribution side current is more so copper losses are more, so distribution side transformers are designed to have less winding resistance, so that the copper losses are low.

How do you use distribution transformer as temporary power supply to residential housing?
A distribution transformer IS the term used to describe the utility transformer which supplies a residence.
What is maximum efficiency condition in distribution transformer?
The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss

What is the difference between an isolation transformer and distribution transformer?
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)
Can be a distribution transformer be bidirectional?
Transformers are inherently bidirectional.
What kind of transformer is used to change the voltage of electric current in transmission lines before it enters houses in a neighborhood?
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
Distribution transformer vs power transformer?
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
What is the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
How do you design a transformer with three phase 400v input and single phase 2000v output?
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
What is a loop feed transformer?
A loop feed transformer is an electrical device used in power systems to facilitate the connection of multiple power lines, enhancing reliability and efficiency. It allows for the distribution of electricity from two or more sources, enabling supply continuity even if one source fails. This type of transformer is typically employed in distribution networks to improve load balancing and reduce losses. Its design aids in maintaining voltage stability across the connected circuits.
What are the causes of overheating of distribution transformer?
poor cooling mechanisms, and overloading.
