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'.
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
How much output voltage is there if input voltage from a transformer is 32v?
It depends on the turns ratio of the transformer.
The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
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.
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 do you call A device that increases or decreases voltage in a power line is a?
A transformer can perform this function.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the function of step-down transformers?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of Transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
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.
