What is considered to be the primary side on a step down transformer?

Transformers have windings - typically each winding is designated for a particular voltage. Any one of the windings can be an "output", as any winding can be an "input". Usually for consumers, one of the windings is intended to be 120V for the input. In that case, all of the other windings would be an output.
I should also mention that while you can have several outputs, you can only have one input. Some transformers have the windings color coded to designate input and outputs.
Hope this helps!

∙ 9y agoAny transformer has got at least two windings. There is a relationship between the number of turns in primary, secondary and the voltages across primary and secondary windings of such a transformer.
N1V2 = N2V1
N1 = Number of turns in first winding (primary)
N2 = Number of turns in second winding (secondary)
V1 = Voltage across primary
V2 = Voltage across secondary
So for a step-up transformer the secondary voltage V2 will be higher than primary voltage V1. Hence the coil with less number of turns is called primary or low voltage side.
ANOTHER ANSWER
Voltage levels are irrelevant to the terms 'primary' and 'secondary'. By definition, the primary winding is whichever winding is connected to the supply, and the secondary winding is whichever winding is connected to the load. Simple!

Answer
A transformer can be used with either of its two windings connected to the supply. Whichever winding is connected to the supply is termed its 'primary winding' and whichever winding is connected to the load is termed its 'secondary winding'. The rated voltage of the primary winding should match or exceed the rated supply voltage. The resulting secondary voltage should match the rated voltage of the load.

What is the different between et up and set down transformer?
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?
A DC voltage added to one side of a transformer has no effect on the other side.
How does a step down transformer work?
well the working of the step doen transformer depends on the number of turns on the secondary side of the transformer, now in the case of a step down transformer, the number of turns in the secondary windings are less as compared to the number of turns at the primary side/winding, so the amount of flux which links the secondary side of the transformer is also less resulting in the production of less amount of emf at the secondary side. hence the status of the voltage is decreased as compared to the voltage of the primary side.
How does a step-down transformer work?
well the working of the step doen transformer depends on the number of turns on the secondary side of the transformer, now in the case of a step down transformer, the number of turns in the secondary windings are less as compared to the number of turns at the primary side/winding, so the amount of flux which links the secondary side of the transformer is also less resulting in the production of less amount of emf at the secondary side. hence the status of the voltage is decreased as compared to the voltage of the primary side.
Why is the wattmeter connected at the primary side of the transformer?
In general, you can install a wattmeter on the primary or the secondary side of a transformer (it depends what you are trying to measure). But if you are conducting an open- and short-circuit test (to find the transformer's losses), then the wattmeter is connected to the primary side because you want to measure the total (primary + secondary) losses and that is only achievable from the primary side.

Why you uluminium on primary side of transformer?
This isn't the case. You can have aluminium or copper on primary or secondary side of a transformer.
If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?
A DC voltage added to one side of a transformer has no effect on the other side.
What does the term primary side refer to?
The line side of a transformer that is connected to your source or incoming voltage that you are stepping up or down.

Does a basic transfomer in its normal operation use step up voltage step down voltage step up current or all?
A transformer has a primary and a secondary side. There is a ratio of windings from one side to the other that dictates whether it is a step up or step down transformer. The transformer is usually marked as to the input and output specifications. The current is directly proportional to voltage. If you had a transformer that was a step up from primary to secondary, it would be step down from secondary to primary.
Why is the wattmeter connected at the primary side of the transformer?
In general, you can install a wattmeter on the primary or the secondary side of a transformer (it depends what you are trying to measure). But if you are conducting an open- and short-circuit test (to find the transformer's losses), then the wattmeter is connected to the primary side because you want to measure the total (primary + secondary) losses and that is only achievable from the primary side.
Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
What is the line side of the 3 phase transformer?
The primary line side of a 3 phase transformer should be marked H1, H2, H3. The line side is the incoming voltage that you want to step up or step down or isolate.
Does the fuse on the primary side of a transformer protect the secondary side?
Yes, but it's usual to have fuses on both sides of the transformer.
