Ideally the voltage regulation voltage of a transformer should be zero. It means when you change the load from no load to short circuit (theoretically, normally you don't want to burn the transformer windings) the output voltage doesn't change and remains equal to the no load voltage.

What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
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.
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.
Why are large transformers designed not to have optimum regulation in order for circuit breakers to be within reasonable size?
Transformer voltage regulation and size of the circuit breakers have no direct relation

What is voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.
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.
When voltage regulation will be zero it operate it?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.

What do you understand by regulation in a transformer?
Regulation of transformer means percentage reduction of transformer secondary voltage due to transformer loading as compared to its no load voltage.Another AnswerA transformer's voltage regulation is defined as 'the change in its secondary voltage, from no-load to full-load, at a specified power factor, expressed as a percentage of its full-load voltage, with the primary supply voltage held constant'.

What are performance characteristics of a transformer?
The properties of an 'ideal' transformer are (1) voltage ratio equals turns ration, (2) no losses.
What is the condition for zero voltage regulation of a single phase transformer?
zero volatge regulation means the terminal volatge of transformer at full load on a given power factor become equal to the rated teriminal volatge of transformer , it happens only for leading power factor in transformer
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.
