What is the nominal voltage of a 150 kW 480 v generator?
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…g a light turned on. Answer The 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.

When people talk about 480V systems, they mean 480 is the RMS 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 …the 'named' voltage. For example, the nominal voltage of the supply system in Britain is 230 V. But its actual value is allowed to vary between 216.2 V and 253.0 V.
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…nal 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.
You would need to use a transformer. It would have to come from a three phase system. Residential homes are single phase electrical systems and the only what to get three phas…e 480 volts would be from a generator. This is a common question when someone gets a piece of equipment from a commercial or industrial setting where three phase electricity is commonplace. It is not practical to try to run a 480 Volt, 3 phase piece of equipment at home.
A 20kW generator operating at 3/4 load will burn approximately 1.3 gallons of fuel per hour. So if you only include the "variable" fuel costs to generate electricity, you are …going to get 15kWh of electricity from the 1.3 gallons of fuel. If your fuel costs $3/gallon, this would give you a variable cost of $0.26/kWh. You should be able to use "off road" diesel fuel that doesn't include all of the highway taxes. And you should include the "delivered" cost of the fuel. Of course the real costs to generate electricity from a diesel generator must include all of the fixed costs. You can buy a 20kW generator starting at about $5,000. If it lasts for 10 yrs, then that would only add about 5.5 cents to each kWh. You also need to add in maintenance costs and any installation costs.
A small AC generator rating may be specified in kW, because that is the maximum useful (real) power that can be produced by that generator. If the purpose of the generator is …to run small power tools, some lights, maybe a TV or grill, this is a more useful value for the Average Joe to know. On bigger generators, KVA is usually specified with a specific power factor; Usually a power curve is provided (or can be requested) with these showing their operating capabilities at different power factors. At utility sizes, this is much more useful information (than just a kW or MW rating), as the real and reactive power must be controlled on the power system to keep everything in a stable state.
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…er designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
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 …230 V, because the supply voltage is allowed to vary by -6% and +10% of the nominal voltage. In other words, the actual voltage could be anywhere within the range of 216.2 V to 253 V. In fact, during periods of heavy load, the actual voltage would tend towards the lower end of this range, whereas during periods of higher load, the actual voltage would vary towards the upper end.
By using a gas engine to drive a dc motor. Motors are cool in the way that if you give them power they will spin and if you spin them they will make power. There is a ball of …coiled wire in a motor and when it spins the magnets in it try to resist the spinning but if it succeeds in spinning then electrons will be pushed through the coils by the resistance of the magnets and ultimately through your electrical appliance's.
'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 valu…es, not their actual values which can change from moment to moment.
It is typically accepted to be 440 to 500, based on 110 to 125V for common power outlets. This is based on experience in the USA with 60Hz power supplied by utility companie…s. Since 3-phase is mentioned, you should also state if this is delta or wye configuration, and whether you are measuring from phase to phas or phase to neutral. For a more competent answer, an electrician should refine this answer, or you could look up the relevant standard, probably an ANSI standard.
Whoa, this is a serious motor! The generator needed would cost in the neighborhood of $50,000.00 US, would require permits to install and run, and would require professi…onal installation. Check your telephone directory for generators. 270v is an unusual number in the US, what country are you in? Curiously, if this is a 3-phase motor, your numbers don't add up. 270v at 200a is only about 93kw of electrical comsumption, this motor would not be able to produce 185kw of output.
A 480 v three-phase system has 480 v between live lines and 277 v from each line to the neutral. This type of supply is common in North America for supplying for example s…mall factories that need more power than a 120/208 v three-phase system can supply.
