What is the set up for a transformer that decreases the voltage on the out put side?

A basic, two-winding, transformer consists of two, separate, coils (called windings) wound around a laminated silicon-steel core. The winding connected to the supply (input) is called the primary winding, and the winding supplying the load is called the secondary winding.
Alternating current flowing in the primary winding sets up an alternating magnetic field in the core which induces a voltage into the secondary winding. If there are fewer turns in the secondary winding, then the secondary voltage is lower than the primary voltage. If there are more turns in the secondary winding, then the secondary voltage is higher than the primary voltage.

Is it possible put a 33 kv to 400 v electric transformer inside an apartment building?
Yes, many large buildings are built with electrical vaults to house the electrical distribution system. The high voltage enters the building usually underground, where it connects to a transformer. The secondary side of the transformer is connected to a distribution system where the supply voltage is then sent to the individual apartment sub panels.
Can you put transformers in series to double your voltage?
You can if done carefully. The neutral of one transformer must be set up to be at the positive voltage of the other transformer. This might require an intermediate step transformer that is center tapped (so three instead of 2 transformers).
What is the difference between a secondary and primary coil?
The primary coil is the one with voltage applied, or the 'input'. The secondary coil is the one in which a voltage is induced by electromagnetism, or the 'output'. In a step up transformer, the secondary coil voltage is higher than the primary. In a step down transformer, the secondary coil voltage is lower than the primary. In an isolation transformer, the secondary coil voltage is the same as the primary. Here, the point of the transformer isn't to raise or lower voltage, but to keep a particular circuit electrically disconnected from another circuit, while still allowing the circuits to function together (through electromagnetism).
You have 480 volts coming into a stepdown transformer that is set for 440 volts incoming power would this cause your output voltage to be higher than 120 volts?
In short, probably. Transformers step power up or down by a multiplicative factor based on the number of turns in the two transformer coils. Therefore, if you put more voltage in you're going to get a proportional increase in the voltage out.
How many amps on 25 kva transformer 1phase secondary 230 volts?
Take the KVA and divide it by the voltage. 25/.230 = 109 amps. The transformer can put out up to 50% more that its rated for short durations. So you could get around 150 amps out of a 25 Kva tranformer in a worst case situation.
Why arcing horns are used on primary side of transformer?
It's common to put arcing horns on the HV side of a power transformer to short out voltage spikes arriving from lightning strikes along the line.
What does a step-down transformer do to the electrical current?
A step-down transformer lowers the voltage of an AC current. The higher AC current is put through one side and the other side the lower AC current is delivered.
Can you put a transformer on a 32 amp generate to drop the amps to 16 amps?
The purpose of a transformer is to transform one voltage to another voltage. This can be in the configuration of stepping up the voltage or stepping down the voltage . The load is what establishes what the current from the transformer is going to be.
How do you solve low voltage supply?
Put a seprate transformer. It will solve this issue
Can a transformer increase the 12 volt of electric charge into desirable voltage?
A transformer can change any AC voltage to any other AC voltage. But if you put DC into a transformer, the main component at the output is smoke. Furthermore, sir, you have insulted 12 volts by implying that it is undesirable.
Do the induced voltage increase in a transformer when the magnetic field strength increase?
Yes, the more voltage you put in the more you get out. If the transformer is a 2 - 1 ratio and you put 240 in you get 120 out and when you put 480 in you get 240 out. Magnetic field strength and voltage have a direct relationship. +++ The field strength is actually a function of current, although as you say, increasing the voltage will increase the current hence the magnetic field.

How does a stabilizer?
A home voltage stabilizer reduces (buck) or increases (boost) the out put voltage for respective increase and decrease in line voltage. To reduce output voltage the relay cutoff some transformer winding turns, and to increase output voltage the relay add some transformer winding turns in predefined steps.

What is the best fire extinguisher for height voltage transformer?
the best fire extinguisher for high voltage is a c extinguisher because it can put out electrical fires
What do you mean by no load of transformer?
Transformers voltage ratings are typically at full load. For instance, A 24 VAC, 10A transformer will have a terminal voltage of 24 when it is feeding 10 amps to a load. Since the transformer windings have some resistance, the transformer designer has to wind the transformer to put out more than 24 volts, since some of the voltage will be lost, dropped across the resistance of the secondary windings. But, according to Ohm's law, the voltage dropped across a resistance is proportional to the current (E=IR). If we take away the 10A load, there is no current, and therefore no winding voltage drop! The excess voltage the designer built in now appears at the terminals. This is the no-load voltage. In my example above, when we remove the 10A load, the output voltage of the transformer might rise to 26.4V. We would say the no-load voltage of that transformer is 26.4V The ratio of full-load voltage to no-load voltage is called the transformer's "regulation factor". It is calculated as: (no-load voltage - full-load voltage) / full-load voltage * 100. Ours is: ((26.4 - 24) / 24) * 100 = 10%.
