How many volts does the average transformer have?

Question

Is it anywhere near 1,000,000 volts?

Answer 1

They can be any voltage. It depends on what the transformer is being used for.

Answer 2

Transformers come in so many different sizes, handling anything from miliwatts of power to hundreds of megawatts, I don't think it is possible to say what the average transformer is. The main power transformer at a power plant might convert 25,000 volts to 365,000 volts. The transformer which runs your door bell converts 110 volts to 40 volts. The transformer in your computer's power supply converts 110 volts (or 220 in some countires) to 12 volts and 5 volts. A dynamic microphone has a little transformer which converts millivolts to about a volt.
. There are transmission lines which operate at 1,000,000 volts, so there must be transformers to convert this down to distribution line voltage (about 4160 volts).

Answer 3

There is no such thing as an average transformer. If I had to guess which is the transformer most commonly used (and call that one average) I would say it is a transformer with an input voltage of 120 volts and an output voltage of 24 volts. I say that because that is the one usually found in control systems like home heating systems with 24V thermostats.

I would say a 14 volt door chime transformer is next most common.

Answer 4

Transformers are devices which transfer power from the power plant to the household. This is done by stepping down the voltages that leave the power plant and distribute it among many houses. They call this a network or a grid. Some of your higher voltages that run along large metal towers are 69000 volts. It is broken down by transformers at substations to 2400 volts that feed the transformer near your house, which further steps it down to 240 volts that enter your house. So the question is hard to answer.......but the transformers that are by the houses on power poles are usually 4160 / 2400 volts.

Answer 5

it depends on what transformer you're talking about. Some high voltage transmission lines can get up to that. but not the stuff you plug into your wall socket-outlet. A transformer has two sides, an input (where the power comes in from) and one or more outputs. Technically, you can make the input and the output voltages anything you like, with the right size wire and insulation and core material. The output voltage is dependent on the turns ratio of the input winding to the output winding.

Answer 6

Not sure what you mean by the "Average" transformer.

If you consider the voltage on either side of a transformer, the largest number of transformers have 115 VAC on one side ... but what's on the other side is all over the map. I'm guessing that less than 50% have 115VAC on one side, (especially with some countries using 220VAC and all of the low voltage to low voltage stuff out there).

However, transformer technology is being quickly replaced by switching power supplies.

Answer 7

There is no "average" transformer. Transformers are designed for specific applications. If you want to limit your question to that, the question could have a reasonable answer.

Answer 8

Transformer are used in circuits to convert AC voltage from one voltage level to another or to isolate circuit to another. If voltage on secondary is more than what we gives on primary than it is step up transformer and step down if vice-versa.
Transformer are design depending on the voltages u require on primary and secondary and power that transformer will handle ie KVA ratings.

Answer 9

220

Answer 10

There is no "average" transformer. They come in all different shapes, sizes, and specifications.
