'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.

Is it true line voltage 415 volt?
Until the requirement for the UK to conform to EU standards, the standard low-voltage three-phase nominal line voltage was 415 V (+/- 6%). After the adoption of this EU requirement, the nominal line voltage became 400 V (+10%/-6%).
230V line to line a single phase?
Yes. 230V line to line is considered single phase power. The 115v half part of that is called split phase. It should not be called two phase, as it is one phase that has been center tapped and grounded at the neutral point - it is still one phase power.Answer230 V is the standard nominal voltage for residences in Europe. 230 V is the line-to-neutral voltage (phase voltage). Low-voltage distribution is by three-phase, four-wire, system with a nominal line voltage of 400 V and a nominal phase voltage of 230 V.
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 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 nominal voltage and operating voltage?
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 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.

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 line voltage and line current in star connection define?
In star the voltage from line to neutral is 1/sqrt(3) times the nominal voltage, while the load current equals the line current. In delta the voltage between lines is the nominal voltage, while the load current is 1/sqrt(3) times the line current (for a balanced load). So a delta load needs 3 times the resistance compared to a star load of the same power.
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 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 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.

Line voltage is understood to be any voltage?
The Line normally refers to the live wire in a single-phase system and the three live wire of a 3-phase system. In a 3-phase system the line voltage is usually quoted as the nominal voltage, and that is the voltage between any two of the live wires. The voltage between one of the lines and neutral is 1/sqrt(3) times less.
