A voltage transformer (known as a 'potential transformer' in North America) is classed as an instrument transformer. It is used to reduce the voltage across a high-voltage load to a value that can be read (usually remotely) by an ordinary a.c. voltmeter, while electrically isolating that voltmeter from the high-voltage system for the purpose of safety. It can also be used to supply an input to a protection relay.

The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
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 function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
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 differences between a step-down transformer and a step-up transformer?
the main function of transformer is to change the magnitude of Voltage. difference between step up and step down is step up will change the input voltage into a larger magnitude of output while step down is vice versa
The basic function of a transformer is to change?

What is the function of capacitor voltage transformer at the switch yard?
function of capacitive voltage transformer is measure high transmission voltage with low range voltmeter and oprate the relay circuit to oprate CBs.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
How do you produce a step-up transformer in an ordinary transformer?
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
What is the main function of a transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity
What is the main function of the transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity
What are the voaltg in isolation transformer?
The function of an isolation transformer is to electrically-isolate the secondary circuit from the primary circuit, without changing the voltage levels. So, its secondary voltage will be the same as the primary voltage.
What is the primary function of a step-down transformer that distinguishes it from a step-up transformer?
A step-down transformer reduces the voltage from a higher level to a lower level, while a step-up transformer increases the voltage from a lower level to a higher level.
Why transformer is only used instead of any other device?
A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.
What is the function of a thermostat transformer in a heating and cooling system?
The function of a thermostat transformer in a heating and cooling system is to convert the standard voltage from the electrical system into a lower voltage that can be safely used by the thermostat to control the heating and cooling equipment.
What is the purpose of a doorbell low voltage transformer and how does it function in a doorbell system?
The purpose of a doorbell low voltage transformer is to convert standard household voltage (usually 120 volts) to a lower voltage (typically 16 volts) that is safe for the doorbell system to operate on. This transformer is essential for powering the doorbell chime and button, allowing them to function properly without the risk of electrical hazards.
What do you call A device that increases or decreases voltage in a power line is a?
A transformer can perform this function.
