A transformer will operate with a voltage regulation of zero when it is not supplying a load.
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'.
ic voltage regulator is good for line or load regulation
Regulation has to do with keeping the voltage at a desired value. This is often put in a per unit value, which you can think of as a percent of nominal. So if the desired voltage is 34.5kV, and the actual voltage is 33.8kV, the voltage is .98 per unit. There are regional and national rules on how low or high voltage can be. If the voltage strayes from this, it must be regulated back to an acceptable value.
It has poor regulation and wastes energy.
yes.. voltage regulation can be negative
Percent Regulation is the regulation expressed as a percentage is a figure of merit used to specify the performance of a voltage regulator.
The change in output voltage from no load to full load defines the voltage regulation of that transformer.
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
'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.
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.
To regulate the voltage
People have used a ballast for current regulation and you can use a breakdown diode for voltage regulation.
