its also named as potential Transformers...it is one type of instrument transformers used to measure high range voltages using low range volt meters. basically it is used to extend the range of meters.

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.
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 the difference between variable transformer and ordinary transformer?
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
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.
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.
When is a step up transformer used in relationship as to when a step down transformer is used?
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.
Does a transformer provide electrical energy that is produced chemically?
No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.
What is voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.
Why the capacitive voltage transformer and voltage transformer both are used in a substation?
three phases
What is a transformer called that increases voltage?
A transformer that increases voltage is a step-up transformer.
How much output voltage is there if input voltage from a transformer is 32v?
It depends on the turns ratio of the transformer.
What is the voltage doubler using charge pump?
What is the math in a voltage doubler without a transformer? how doesa voltage doubler without a 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.
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
