What is the normal allowable source voltage deviation from the motors nameplate voltage rating?
It can be 10% min and 5% max.AnswerA nameplate voltage is a 'nominal voltage', and manufacturers normally design their products for the allowable variation in nominal voltage of the country in which they are to be marketed. So, for those products intended for, say, the British market, manufacturers would take into account the British allowable variation, which is 230 V (+10%/-6%). And, no doubt, most manufacturers would widen this variation to allow a 'factor of safety' for their products.
What is the UK 3 phase voltage?
The nominal voltage in the UK is 400/230 V. That is 400 V line-to-line (i.e. line voltage), and 230-V line-to-neutral (i.e. phase voltage). Allowable variation is +10% and -6%.
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
At what phase angle is the voltage momentarily constant in a sine wave?
We often see the peak and trough (maximum positive and maximum negative excursions) of the sine wave considered as points of momentarily constant voltage. Those points are at phase angles of 90 degrees and at 270 degrees.
Why clipping happen for op-amp?
Clipping occurs in the voltage waveform when the input voltage, multiplied by the voltage gain of the op-amp circuit, exceeds the op-amp supply voltage as limited by the output network. The supply voltage and output network, limits the maximum voltage that can be achieved at the output. The op-amp behaves normally within its range of maximum voltage output, and then it is clipped when it reaches the maximum voltage of the circuit.

What is maximum voltage for residential low voltage circuits?
The answer to this question depends entirely on where you live. All voltages quoted are 'nominal', or 'named', voltages and not the actual voltage as you would measure it with a voltmeter. National regulations stipulate how much these nominal voltages may vary.For example, in the UK, the nominal voltage is 230 V, and the allowable variation is between -6% and +10%. So, the maximum (actual) allowable voltage is 253 V.In some residences, e.g. Cyprus, a three-phase supply is common for residences, in which case the maximum nominal line-voltage is 400 V, with a nominal phase-voltageis 230 V.
How do you determine the minimum allowable voltage between line and neutral?
The voltage between line and neutral is determined by the regulations in your country. This is specified as a nominal (named) voltage, together with its allowable variation expressed as a percentage of that nominal value. In the UK, for example, this is 230 V (+10%/-6%).
What is the UK 3 phase voltage?
The nominal voltage in the UK is 400/230 V. That is 400 V line-to-line (i.e. line voltage), and 230-V line-to-neutral (i.e. phase voltage). Allowable variation is +10% and -6%.
Are 250 voltage reading considered to be nominal 240 volts?
Different countries have different legal limits to how much their electricity supply voltages may vary. In the UK, for example, the nominal supply voltage for residential supplies is 230 V, but this is allowed to vary between -6% and +10%. So, as you can see, and 'actual' voltage of 250 V is within the allowable upper limit (253 V) for the nominal voltage of 230 V. So, to answer your question, you need to check what the allowable variation is at your location (your electricity supplier can confirm this) -I would guess that 250 V would be well within the allowance for 240 V.
What is the allowable voltage level for a hand held lamp?
220V
Can voltage increase or decrease in a system during a day?
Power supply voltages vary with the amount of load placed on them. In many countries the supply voltage has a nominal voltage and a plus or minus tolerance. In the UK the nominal voltage is 230 v but the allowable variation is -6% +10%, in other words 216-253. At my house the voltage is usually between about 236 and 253 volts.
Maximum generating voltage in world?
maximum generated voltage is 21KV
What is the minimum allowable voltage during load of 70 degrees Celsius?
There is no minimum
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.
What is the maximum charging voltage for a 12-voltage gel cell battery?
15.5 volts maximum.
What is the exciter voltage needs to test the generator?
Because the voltage is fixed (within allowable limits) whereas the current varies according to load.
