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.

Frgi transformer
Where are three phase transformer systems used?
Any where that a three phase supply distribution is needed to operate three phase equipment.
Is there a neutral on a three phase transformer?
It depends on whether you are wye or delta connected. A transformer is a transformer, and a three phase transformer is simply three transformers. The key is in how you hook them up.AnswerIt depends on how the transformer is connected. If one set of windings is connected in star (or wye), then the star point is/canbe earthed and becomes the neutral for that particular connection; this is the standard connection for the secondary (low-voltage) of European distribution transformers. In North American three-phase distribution transformers, the secondary windings are connected in delta, and one phase is centre tapped, earthed, and that becomes the neutral point for a 240/120-V split-phase supply to a residence.This answer applies to both three-phase transformers, and to single-phase transformers which have been connected to form a three-phase transformer bank. (It is incorrect to say that a three-phase transformer is simply three single-phase transformers!)
How electricity gets from the generating plant to an appliance in a home?
through: wires, transformers, breakers, switches, etc.Something like:Power plant wires carry electricity to plant switching farm.Switches in switching farm direct electricity to step-up transformer for a transmission line.Step-up transformer increases voltage to reduce transmission losses.Wires from step-up transformer go to high voltage breaker to protect switching farm from transmission line current spikes.Transmission line wires attach to breakers and leave plant switching farm.Transmission line wires run hundreds of miles to consumer locations.Transmission line wires enter a distribution switching farm and attach to high voltage breakers to protect switching farm from transmission line current spikes.Wires from breakers go to step-down transformer to decrease voltage for safe distribution.Wires from step-down transformer go to switches in switching farm.Switches in switching farm connect electricity to desired distribution lines.Each distribution line has breakers on it to protect the switching farm and the line.Distribution lines run to various neighborhoods.At each customer location the distribution line connects to a step-down transformer to reduce the voltage to what the customer needs (e.g. U.S. residential 120V/240V 2phase).Wires connect the step-down transformer to the customer's fuse/breaker box and distribution panel.
What is the purpose of a transformer?
It steps down voltage by moving the iron core spacing. Mostly using on high current welding transformer. Easy to achieve changing output voltageand does not need to use high power selector to switch voltage
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 the maximum transformer rating for distribution transformer?
100MVA
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
GE distribution transformer serial?

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.
Is current transformer is a distribution transformer?
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
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'.

What are the causes of overheating of distribution transformer?
poor cooling mechanisms, and overloading.
