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'.

∙ 11y agoTransformers don't do voltage regulation they do voltage conversion. So you need something else to do the regulation because it can only multiply an (AC) voltage by some predetermined constant. So if they input voltage is not stable, then neither will the output.
AnswerA transformer's voltage regulation is defined as 'the variation of secondary voltage, from no-load to full-load, expressed either as a per-unit or percentage of its no-load voltage'. In other words:
voltage regulation = (no-load voltage - full-load voltage) / no-load voltage

∙ 15y agoRepresents percentage drop in voltage (With basis as full load in U.S., or basis as Vopen circuit in U.K.) when load is applied- Regulation in U.S. is (Vno load - Vfull load)/ Vfull-load x100 Regulation in U.K. is (Vno load - Vfull load)/Vno-load x 100

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 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
How efficient is a transformer when changing voltages?
A: Must understand this A transformer transfer power minus efficiency to another level that all it does.
How the voltage regulation in 33kv line?
It does not depend on the line. The regulation is the percentage change in voltage caused by applying the full load current, and that depends on the transformer supplying the line. A value of 5% would be typical.
What is no load tap changing in transformer?
It changes the tap while it is operation (hence "on load"). This allows real-time voltage regulation for the transformer secondary (as load picks up, causing the voltage to sag, the LTC can tap up, increasing the voltage).
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 voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.
What is the effect of transformer impedance 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.
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 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 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 condition you get negative regulation for transformer?
When its load has a leading power factor.
Diagram of voltage regulation of a transformer?

What is the voltage regulation of an ideal transformer?
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 are the purposes of performing no load test for the transformer?
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.
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 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.
