What is nominal line voltage?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

'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.

Why is it not good to operate a transformer above its nominal voltage?

Overexcited Transformer.  Operation above the rated supply voltage causes the ferromagnetic core to enter saturation; this means that the primary inductance is reduced and s

What is the difference between line to line voltages and phase voltages?

The conductors that connect a three-phase supply to its load are  called 'line conductors' or, more simply, 'lines'. The individual  generator stator windings, transformer w

What is meant by nominal current or nominal voltage?

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 keepin

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 supp

What is nominal voltage?

It is the rated voltage of an electric equipment. It is the voltage at which the device is designed to operate. Another Answer Nominal means 'named'. So a nominal voltage is

What is phase voltage and line voltage?

The three 'hot' conductors supplying a three-phase system are called 'line conductors'.  A line voltage is the voltage between any pair of line conductors. In a 'delta' conne

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 nomi

Why is phase voltage not twice line voltage?

Line to line voltage is not the same as line to neutral voltage because line voltages are 120 degrees apart. They are related by: Line to neutral voltage * tan (120 degrees) =

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 manufactur

What is the nominal supply voltage?

The term, 'nominal', simply means 'named'. For example, the nominal supply voltage for a residence in the UK is 230 V. But this doesn't mean that the actual supply voltage is

Is line to line voltage equal to line voltage?

Yes. By definition, a line-to-line voltage is indeed called a line voltage. For delta-connected, three-wire, systems comprise three line conductors. The line voltage is nume

The question and answer are locked and cannot be edited.

How do you convert voltage line to voltage phase?

For questions of this type, it seems the main issue may be one of definitions and industry terms. See if this makes sense: Line voltage is a very ambiguous term. For instance

Can i use a circuit breaker with 420V nominal voltage in 520V line voltage nominal current of circuit breaker is 1600A if I can how much current can pass from this circuit breaker?

  NO! NO! NO!   The circuit breaker must be rated for the line voltage used. Exceeding this limit can cause catastrophic failure!   If you are really working on a 16

What is line voltage that it is understood to be any voltage?

Your question is confusing and probably reflects certain  misunderstandings. But I will attempt to give an answer.    household single phase line voltage is 110 VAC, 11
