It is a type of transformer that you usually see hanging from a utility pole that feeds your house. It transforms the high transmission voltage down to the usable voltage that is used in the home.
around $500 a pole and $2 a foot about $1000 for the pole mounted transformer poles need to be less than 100' apart
yes we can place auto transformer in place of original transformer
A transformer that increases voltage is a step-up transformer.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
In simple you don't. They are screwed in place. It would be too dangerous to hang it.
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
Lower the rating of the primary fuse feeding the transformer.
240 volts from the secondary side of the transformer to your house
If you are referring to a pole-mounted distribution transformer, it's in order to maintain a safe clearance between its high-voltage connections and ground level.

pole-mounted electrical transformer
The transformer steps down the voltage from 600kilo volts which is what is at the power pole/lines to multiple strands of 120v or hot wires which is what your house runs off of.
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.)
There are two types of pole-mounted fuse. One type is a high-voltage fuse, intended to protect the transformer. The other type is a low-voltage fuse, intended to protect the cable or line supplied by the secondary winding of that transformer. The current ratings of these fuses depend entirely on the current ratings of the devices they are there to protect.
Some small control transformers have a built in primary fuse. Larger transformers are primary fused externally and pole transformers are primary fused externally with the fuse holders mounted on cross arms near the transformer.
In North America you can not obtain 230 volts from just one single pole breaker. The distribution is like this, from a one pole breaker to neutral is 120 volts. From an adjacent breaker to neutral is 120 volts. From the adjacent breaker to adjacent breaker (breakers situated beside each other) the voltage will be 230 volts.If you want to incorporate a 120 to 230 volt transformer into the circuit you can obtain 230 volts. The primary side of the transformer will be connected to the 120 volt circuit and the secondary side of the transformer will output 230 volts. The transformer must be sized to the load amperage or the load wattage of the connected 230 volt load.
