A transmission transformer steps the voltage up to a very high value so electricity can travel long distances on transmission lines from the power plant to a city or area with low loss.
A distribution transformer steps the high voltage back down to a level that can be used for local distribution and use by businesses and homes.

A distribution transformer is typically found outside a residential house. These transformers step down the high voltage from power lines to a lower voltage suitable for use in homes.
Any where that a three phase supply distribution is needed to operate three phase equipment.
Transformer is an electrical word that starts with the letter "t." Transformers are devices used to change the voltage of electricity for transmission and distribution.
The type of transformer that can convert from microvolts to volts is a step-up transformer. This transformer increases the voltage level from the input side (microvolts) to the output side (volts) using electromagnetic induction. Step-up transformers are commonly used in power distribution systems to increase voltage for long-distance transmission.
A distribution transformer IS the term used to describe the utility transformer which supplies a residence.

The maximum efficiency condition in distribution transformer is said to be occurred when iron loss = copper loss

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.)
Transformers are inherently bidirectional.
In transmission lines there is a massive current, we use CT to make this current measurable i.e. it steps down the current but DT is used to step down the voltage
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
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.
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'.
