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 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 instantaneous voltage at 180 degrees for peak voltage of 150 volts?
Zero. If voltage starts at zero at zero degrees, it rises to peak voltage at 90 degrees. Voltage then reaches zero at 180 degrees and heads for negative peak voltage at 270 degrees and then back to zero at 360 degrees.
What is zero voltage switching?
Zero Voltage switching is a standard used to describe electrical appliances which turn on or off only when the output voltage is Zero.
What is voltage regulation?
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.
Why is the voltage across a battery in a parallel circuit equal to the voltage across each bulb?
The voltage across a battery in a parallel circuit is equal to the voltage across each bulb because Kirchoff's Voltage Law (KVL) states that the signed sum of the voltages going around a series circuit adds up to zero. Each section of the parallel circuit, i.e. the battery and one bulb, constitutes a series circuit. By KVL, the voltage across the battery must be equal and opposite to the voltage across the bulb. Another way of thinking about this is to consider that the conductors joining the battery and bulbs effectively have zero ohms resistance. By Ohm's law, this means the voltage across the conductor is zero, which means the voltage across the bulb must be equal to the voltage across the battery and, of course, the same applies for all of the bulbs.
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.

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
Why an ideal voltage regulation of a device has zero value?
An ideal regulator would hold the thing it is regulating (e.g. voltage, current, water pressure, motor speed) absolutely constant, or in other words with zero variation of that parameter. The quality of regulation in actual regulators however can only approach this ideal of zero variation.
If voltage is zero so will current be happened?
No voltage means no current can flow.
At what condition the phase angle equal zero?
That means that the voltage and the current are in phase.
Why the voltage is same in parallel connections?
The voltage is the same across parallel inductors for the same reason its the same across parallel anythings - resistors - capacitors - transformers - whatevers. Parallel means sharing common connections to another part of the circuit. That sharing involves conductors that have essentially zero impedance. (Zero for all practical considerations) In order for there to be a different voltage across those parallel components, the conductors connecting them together must have something other than zero impedance, and then we would not be talking about parallel anymore. (Ohm's Law: Voltage is Current times Resistance. If the resistance of the conductor is zero, then the voltage across the conductor must also be zero - it does not matter what the current is.)
What the amount of energy in an electrical charge?
zero. Energy is the product of charge and voltage, E=ev. No voltage means no energy in charge.
Is the amount of energy in an electrical charge?
zero. Energy is the product of charge and voltage, E=ev. No voltage means no energy in charge.

What is the instantaneous voltage at 180 degrees for peak voltage of 150 volts?
Zero. If voltage starts at zero at zero degrees, it rises to peak voltage at 90 degrees. Voltage then reaches zero at 180 degrees and heads for negative peak voltage at 270 degrees and then back to zero at 360 degrees.
