An ideal transformer (one with no losses, and not a bad approximation for the real thing) has an input power equal to its output power. In simple terms, since power is the product of voltage and current, then for a given value of power, as the voltage goes up, the corresponding current will go down.

Can you use a transformer to compensate the voltage drop in a branch circuit?
If the voltage drop is excessive, it is a sign that the circuit conductors may be undersized. Better to install larger conductors. If you try to use a transformer, under light loads the voltage will rise to unacceptable levels, possibly damaging equipment.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
What causes a low voltage in the transformer?
If this refers to a wire wound transformer, as it sounds then there is likely only two possibilities : the input voltage has dropped prier to entering the primary windings or there is a short in the windings some where within.The only other possibility I can think of is : This is a trick question and the transformer is a step down transformer.
Can a high voltage transformer be megged with a megger meter?
No. A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution transformer or power transformer. Instead, a high-voltage test set or 'pressure tester' (e.g. a 'HiPot' tester) must be used, as these produce far higher voltages.
What is inherent voltage regulation of an onload tap changer for power transformer?
depending on the amount of the load of transformer as well as the power factor of it, there is a transformer specific voltage drop at its terminals, due to the internal impedances. The on-load tap changer can / will be used to compensate this voltage drop or rise.
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.
What is the effect of transformer impedance on regulation?
The lower the impedance, the lower the voltage drop across the transformer as it is loaded. This means regulation is better, since voltage variance is smaller.
What is the effect of low impedance transformer on regulation?
The lower the impedance, the lower the voltage drop across the transformer as it is loaded. This means regulation is better, since voltage variance is smaller.
Can you use a transformer to compensate the voltage drop in a branch circuit?
If the voltage drop is excessive, it is a sign that the circuit conductors may be undersized. Better to install larger conductors. If you try to use a transformer, under light loads the voltage will rise to unacceptable levels, possibly damaging equipment.
How do you get 12 volts from an 18 volt transformer?
Reduce the primary voltage and the secondary will also drop.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
Why voltage in transformer suddenly increases and then decreases suddenly?
In perfect condition, the voltage variations does not occur.. Due to failure causes, voltage variations will arise
Why is it using low resistance coils in transformer minimize power loss?
To avoid voltage drop in the coil.
Does a step-down transformer increase its voltage and and decrease it's current?
No. A step-down transformer's secondary voltage is lower than its primary voltage. The secondary current is determined by the load, and this causes a higher current in the primary winding.
What is difference between breakdown voltage and dielectric strength of transformer?
The dielectric strenght of a transformer represents the maximum voltage permissible to apply across the transformer insulation i.e. between the transformer winding to another part of the transformer, normally the chassis or another winding and without break-down of the insulation ocurring (e.g. arcing). The breakdown voltage of a transformer represents a voltage that exceeds its dielectric strenght and that causes breakdown e.g. arcing across the insulation.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
