What is inherent voltage regulation of an onload tap changer for power transformer?
Wiki User
∙ 15y ago
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.

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 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 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 on load tap chenger?
A tap changer is used to vary the turns ration between the windings of a transformer to make minor changes to the secondary voltage. An on-load tap changer enables the turns ratio to be altered without disconnecting the transformer. An off-load tap changer requires the transformer to be temporarily diconnected. On-load tap changers are installed on the high-voltage side of the transformer, where the current is lower.
What are the possible result of a tap changer malfunction?
Low voltage, high voltage, or a fault; the effects of these could be damage to equipment, including the transformer and tap cahnger.
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.
Why you tapchanger fix in transformer hv side?
A tap changer is used on the high voltage (HV) side of a transformer to adjust the voltage ratio and maintain a desired voltage level under varying load conditions. It allows for voltage regulation and compensates for voltage fluctuations in the power system. By changing the number of turns in the transformer winding, the tap changer can increase or decrease the voltage output, ensuring a stable and reliable power supply.
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.

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 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 is voltage ratio of shell type transformer when the load is changed?
The ratio of a shell type transformer does not change based on load, unless a load tap changer is used. The primary windings to secondary winding ratio is a constant. The voltage on the secondary may be dragged down if loading is heavy, specifically if the transformer has poor voltage regulation. If this is the case, you can infer the voltage on the secondary may float higher than desired under no load conditions.
