What is the Difference between nominal voltage and operating voltage?

∙ 13y ago
Nominal voltage is the 'named' voltage -for example, the nominal supply voltage in the UK is 230 V. But this is not necessarily the actual voltage at a particular time. A nominal voltage is normally expressed together with the percentage by which it is permitted to vary from that stated value. For example, in the UK, the nominal voltage is expressed as: 230 V +10% / -6% --in other words it is allowed to vary between 216.2 and 253 V.
The term, operating voltage, isn't actually defined anywhere, but is usually taken to mean the actual voltage supplied to a device at any particular instant, and this should always fall within the allowable range of the supply system's specified nominal voltage. The operating voltage can be found simply by measuring it with a voltmeter.

What is difference between nominal and terminal voltage?
The rated voltage of a motor listed on the nameplate is called the terminal voltage. This indicates the actual voltage on the motors terminals at which at which the manufacturer designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
What is meant by a nominal current?
The word nominal means the lowest possible safe amount. So, nominal current or nominal voltage is the lowest amount necessary to perform an electrical function like keeping a light turned on.AnswerThe original answer is incorrect. 'Nominal' simply means 'named'. So a 'nominal voltage' is the 'named voltage', as opposed to an 'actual voltage'. For example, the nominal voltage of residential supplies in the UK is 230 V; however, this value is allowed to vary between +10/-6% of the nominal voltage. In other words, a nominal voltage of 230 V may vary between 216 V and 253 V.
What is the Difference between supply voltage and input voltage?
no difference...
What is nominal line voltage?
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
What is nominal zener voltage?
A zener diode has a voltage when it reachesbreak over it may be 5v 12vor other voltage as manufactured. The manufacture will produce a 5v zener or is it? This voltage can change from device to device but the mean or nominal voltage will be as close as 5v as possible. So when buying a 5v zener do not expect 5v absolute but a nominal 5 v ZENERS are designed for a specific voltage [ THEREFORE NOMINAL] as mentioned above . depends on the voltage required it can be bought within a specific voltage -/+ a % of the breakdown

What is the voltage a frequencies of mains electicty?
It depends on where you live, as most countries have their own standards. In the UK, for example, the nominal (named) mains voltage is 230 V, but it is allowed to vary between +10% and -6%. The nominal frequency of this voltage is 50 Hz, and this is allowed to vary between +/-1%. In North America, the standard nominal supply voltage is 120 V at 60 Hz.
What is the Difference between supply voltage and input voltage?
no difference...
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 voltage is a duracell dl123?
The nominal voltage of a Duracell DL123 battery is 3 (lithium) nominal volts or 3.6 (Li-ion) nominal volts.
What is nominal line voltage?
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
Can you use a 230 Volt 1 phase motor with 208 volt 1 phase?
230 V is the standard nominal voltage in the UK. 'Nominal' means the 'stated' voltage, but this is allowed to vary, under government legislation, between +10% and -6%, which means it is allowed to drop to 216 V.The motor's rated voltage of 208 V is also a nominal voltage, but is not a standard UK nominal voltage so, without knowing what in which country the motor is manufactured, we'll assume that it is allowed to vary between, say, +5% to -5%. This means that it can operate at voltages up to 218 V. If it's allowed to vary between, say, +10% and -10%, then it can be operated up to 229 V.So there is an overlap between the nominal voltage of the supply and the rated nominal voltage of the motor so, in all likelihood, the motor should be able to run with a 230-V supply. On the other hand, there will be times when the supply voltage will exceed the upper limit of the motor's nominal voltage, and this may -over time- lead to a breakdown in its insulation and its ultimate failure.
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.
What is UK 3 pase voltage?
The voltage of three phase is 415v and the colours are brown black and greyAnswerThe nominal line voltage is 400 V, and the nominal phase voltage is 230 V.
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
