The voltage ratio of a potential, or voltage, transformer (PT or VT) depends upon the primary voltage to which it is connected. Accordingly, its voltage ratio varies considerably, as there is huge variety of system voltages throughout the world.
Typically a VT's secondary voltage is standardised at 110 V which will match the full-scale deflection of a voltmeter connected to it (although it can also supply protective relays), while its primary voltage is then matched to the voltage of the system to which it is connected: in the UK, for example:
- 11-kV:110 V
- 33-kV:110 V
- etc.

How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
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 secondary voltage of a transformer with the turn ratio of 5 to1 and primary volts of 200?
The secondary voltage of a transformer with a turns ratio of 5 to 1, and primary voltage of 200 is 40. (5 to 1)
The ratio of coils on the input side of a transformer to coils on the output side is the ratio of the input voltage to the output voltage?
I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
How much output voltage is there if input voltage from a transformer is 32v?
It depends on the turns ratio of the transformer.
How do you calculate transformer voltage ratio test?
Secondary voltage / primary voltage
Current ratio is opposite than voltage ratio in transformer?
Yes
What is current ratio on a transformer?
It's approximately the inverse of the voltage- or turns-ratio:
What is the secondary voltage of a transformer with the turn ratio of 5 to1 and primary volts of 200?
The secondary voltage of a transformer with a turns ratio of 5 to 1, and primary voltage of 200 is 40. (5 to 1)
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
The ratio of coils on the input side of a transformer to coils on the output side is the ratio of the input voltage to the output voltage?
I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
What is the output voltage of a transformer if the turns ratio is 0.5?
It is a Step-Up Transformer which has 2 times voltage in secondary(HV) than primary(LV)
What is approximate turns ratio of the centre-tapped transformer used?
It depends on the voltage ratio of the transformer. If you know the primary and secondary voltages, then you can work it out for yourself.
If a transformer has 20 primary windings and 100 secondary windings and the secondary voltage is 25 what is the primary voltage?
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
