What is shunt regulator?
A shunt regulator is a type of voltage regulation circuit that maintains a constant output voltage by diverting excess current away from the load. It typically consists of a zener diode and a resistor; the zener diode conducts when the input voltage exceeds its breakdown voltage, allowing it to shunt excess current. This configuration provides stable voltage regulation for low-power applications but is less efficient at higher currents compared to series voltage regulators. Shunt regulators are commonly used in applications where precise voltage control is required without significant power loss.
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 load and line regulation?
Load regulation refers to a power supply's ability to maintain a constant output voltage despite variations in the load current, ensuring stable performance under different load conditions. Line regulation, on the other hand, measures how well a power supply can maintain its output voltage when there are changes in the input voltage. Both metrics are crucial for determining the reliability and stability of power supplies in various applications, ensuring that devices receive consistent voltage levels. High load and line regulation values indicate better performance and reliability.
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 factors are affecting the voltage regulation?
Voltage regulation is influenced by several factors, including load conditions, line resistance, and reactance. The distance of the load from the power source can lead to voltage drops due to resistance in the transmission lines. Additionally, the type of load, whether resistive or reactive, affects how voltage is maintained under varying conditions. Power factor and transformer characteristics also play significant roles in determining overall voltage stability.
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.

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.
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 load and line regulation?
