Voltage regulation:(from point of view of electrical machines or generator):
It is the change in voltage in between the full loaded and no loaded condition.
When there are no loads connected the terminal voltage is equal to the generated voltage in the generator. But when load is connected the terminal voltage is found to be lass than the no loaded condition, due to armature resistance leakage reactance.This phenomena is expressed as, % reg=(Vnl-Vfl)/Vfl * 100%.Which is Voltage regulation.
************************************************************
An ideal voltage source has zero internal impedance. A practical one, even a good one, has internal impedance.
With no load on the source, the terminal voltage will have a given value.
Once a load current is drawn there will be a voltage drop across the source's internal impedance, and the terminal voltage will therefore drop. The higher the load current, the higher the voltage drop.
A regulator circuit, added after the source, can counter the effect of the source's impedance and maintain an output voltage which is more constant than the source itself can achieve.

Is percent voltage regulation can be negative?
yes.. voltage regulation can be negative
How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
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.
Which electrical component regulates current and voltage?
People have used a ballast for current regulation and you can use a breakdown diode for voltage regulation.
What effect does low impedance have on voltage regulation?
raised voltage output
Is percent voltage regulation can be negative?
yes.. voltage regulation can be negative
Which is better 3 percent voltage regulation or 5 percent voltage regulation?
Percent Regulation is the regulation expressed as a percentage is a figure of merit used to specify the performance of a voltage regulator.
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 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.
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.

'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.
What is line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What is the need of regulation?
To regulate the voltage
Which electrical component regulates current and voltage?
People have used a ballast for current regulation and you can use a breakdown diode for voltage regulation.
What effect does low impedance have on voltage regulation?
raised voltage output
What is alternator voltage regulation?
change in voltage from no load to full load
