Q:hi i am looking for a generator to provide roughly 25kv for home use. roughly the need is4-5 1.5 ton ac3 fridge3 lcd 32-60 inch6 fansa15-20 lights2-3 computer/laptopmultimedia system2 water pumpssome additional usual house requirementswhat option do have on the basis of following:initial costdiesel / petrol / natural gassizenoise leveloperating costoverall efficiencyi personally like HONDA, but they have only 6.5kv available in pertol/gasi want to avoid diesel due to cost and bad fumesin petrol i can make it convertable to gas as wellbut people guide me that if i go in 25kv than the option is only for diesel.pls guide me.imran.

I guess it depends as to the level of comfort you want to maintain during an outage. Do you want to run all the AC units while on generator power or can you be comfortable with only one running at a time? Needless to say natural gas is the most dependable fuel in most cases. Also, there are no storage problems as with petrol and diesel. A 20 KW Generac natural gas generator with a 200 amp automatic transfer switch can be purchased for less than $5,000.00. I can only guess at the cost of installation. We had a devastating ice storm here 2 years ago and I have since installed many of these whole house systems including my own. In most cases the installation costs were less than $1500.00. (plumbing and electrical) This should power your home adequately in most emergency situations. The noise level is easily controlled with the placement of the generator in relation to your home's living and sleeping areas. Operating costs will exceed your normal energy cost as the generator will run at full speed 24/7 and cost will also increase in relation to fuel comsumption depending on the load. Probably about double your normal energy cost. Good luck!

Q:Any places that can supply CHEAP diesel generators.i don't care about the voltage output.Price range about ?100 - ?300.

in many situations, the cost of electrical energy produced making use of diesel turbines is larger than the cost of financial capacity, extraordinarily while the capital cost of the technology is taken under consideration. besides the undeniable fact that, there is one occasion the place the economics would be skewed in desire of working with technology. In maximum advertisement circumstances, the cost shape imposed by capacity of the appliance business enterprise incorporates a 'call for cost'. it quite is a element it quite relies on the utmost point of intake recorded over a quick quantity of time (usually 15 to 30 minutes). as quickly as that call for point has been regular, the financial venue would be charged for that call for for a quantity of time, often a 300 and sixty 5 days or greater. the reason for it particularly is that the appliance could build the infrastructure necessary to help that era of top intake, and regardless of regardless of if that time of intake is maintained, the appliance needs to cost for that top for a protracted era to get well the cost of that infrastructure. So this effects in the area the place a overall performance venue, which would be empty and unused for 29 days out of a month, would come to a determination that it quite is decrease priced to lease diesel technology to help a single overall performance on the 30th day quite than possibility setting up a severe top call for in the process the overall performance that it might finally end up determining to purchase for a 300 and sixty 5 days or greater. And if actuality it quite is comparatively ordinary for overall performance venues or recording studios to take this attitude, and there are agencies that have been geared up up around the variety of imparting condo technology kit especially for those purposes.

Q:I have a 1992 chevy 250 with a 6.5 turbo diesel, I have built a hydrogen generator for it that produces 2lt./min. but do not know how to hook it to the truck or where before or after the turbo.

You should hook it up before the turbo. After the turbo is pressurized which will make it hard to feed the gas in.

Q:i have 350kw old diesel generator and want to calculate the exact consumtionption at various loads.

You will need the specific fuel consumption of the engine, but it is probably close to 0.5 pounds per HP hour or 250g/KW.h. That is specified for the output shaft power at the operating RPM. It depends whether you have a turbo charger, the fuel a little, the air temperature and barometric pressure. Make sure exhaust and air intakes are not restricted too. You may find for a gen-set that you get a set of curves with the fuel consumption for different KW output. These account for the alternator efficiency already. Contact the engine supplier etc for this info. Use KWh from the generator (volts x amps x time gives KVAh not KWh). The amps might be up to 20% higher, depending on power factor of the load. The reactive part of the load does not need power from the engine. This is why I say to use KWh not KW, as you can use ordinary KWh meters (which ignore the reactive load). Allow for the efficiency of the generator (which varies somewhat, especially at light loads). Let's say 85%. Remember it is exciting the field, so that must be included in the efficiency. Thus if you are using 350KW for one hour, the engine provides 350KWh/0.85 411.8KWh (412KWh). The fuel used is 412KWh x 0.25Kg 103Kg of fuel. Now you need the specific gravity of the fuel you are using. You can call the fuel distributor. Ideally this is corrected for temperature of the fuel with the engine running, remembering the engine heats the fuel in the day tank due to recirculation. Let's assume 0.85 is the SG, so that means 0.85kg/l so 103Kg of fuel is 103/0.85 121 liters. In practice it may be higher, especially if the engine is old and worn. This answer is something like the maximum consumption, full rated output, 121 liters per hour. OR 26.6 imperial gallons or 32 US gallons per hour.

Q:How much would it typically cost to rent a 6000-8000watt diesel generator for a week? I know no one here probably knows for sure, so I'm just looking for ballpark figures. Thanks.

You can expect to spend between $60-$80 per day for a diesel generator.

Q:How much power does the generator from the diesel need to produce in order to bring the train up to running speed?

That all depends upon a number of things. First is the type of traction motor that is driving the wheels. Next is the weight of the entire load to be moved by the traction motors. Also is the grade the load is being moved upon. When a locomotive gets up to speed it might not be using many amps by the traction motors to maintain the speed. However, to start from a dead stop on flat track with a very heavy load it could run as high as 200 or more amps. Again, it also would depend upon the number of engines driving the number of generators driving the number of traction motors. A single locomotive might need to use more amps to get up to speed than a combination of locomotives hauling the same load. There are many variables to this question. Given a particular locomotive, types of traction motors, the load weight, it would be easier to calculate what would be needed in amperage. Everything depends upon all of these things. An engineer can burn up a traction motor(s) by exceeding the amount of amps maximum that the motor can handle. The generators don't care, nor do they figure into the problem. The diesels don't care either. They will just turn the generators faster with more RPM's, and the faster they run, the more the generators will produce, but will the traction motors handle what is given them?? It just depends .

Q:Hi. I'm thinking about getting a Kubota Diesel Generator. I have read in many places that the Kubota Diesel engine is the gold standard of Diesel engines. So I'm not worried about that. What i need to know is this, is the generator as a whole dependable? Will over loading it for a few short seconds when the AC compressor kicks in burn it out or shorten its life?Any other insight would be appreciated.Thanks for your answers

Kubota diesel plants are being used more and more in industry, replacing some of the old standbys like Kohler, Perkins and even Caterpillar in lighter applications. I don't think you will regret buying a Kubota.

Q:I know that there is a possibility of explosion, but other than that what makes it such a dangerous job? how else to people get hurt in this line of work? I've always wanted to know this, but I never had anyone to ask!

poor drilling fluids is the main cause of drilling accident,solids control equipment is designed to purify drilling fluids

Q:I want to place a quiete genarator which is about 7kva. Will it disturb people in my apartment? We usually make a lot noise in the building. But doesn't sound a lot also?

a 7kva generator isnt even that quiet. i know they say quiet but theres only so much you can do. why do you need a generator anyways? and yeah it probably would disturb the people in your apartment.

Q:I'm a student majoring in Architecture one of my class, Building Utilities, needs me to survey a high rise building. In my team, we divided the parts bc there are so many and one of my job is to electricity. Can someone explain to me the meaning of phase, R.P.M, power factor, and (especially) their respective units/numbers from this picture

Phase is 3Φ 4W, which means three phase, four wires. Three wires for each of the phases and one wire for the neutral. There are two ways to connect 3 phase generators, ywe which looks like the letter Y (3 or 4 wires) or delta which looks like a triangle (3 wires). Voltage is 380/220V, which means a wye-connected generator with two voltages available. For heavy loads like heating and motors, a line voltage of 380V, measured across two of the phases, is available. For light loads like lights and outlets, a phase voltage of 220V, measured across a phase to neutral, is available. The use of 380V means smaller conductors can be used. When the generator spins at 1500rpm (revolutions per minute), the output frequency is 50Hz. N 120 f / P P 120 f / N 120 * 50 Hz / 1500 4. The generator has 4 poles per phase. Since it is an even number, the generator is a synchronous generator. Prime is the Apparent Power S in kVA that the generator set is capable of providing for an unlimited number of hours per year. In this case 600kVA. But as a Standby Generator (Emergency) operated less than 500 hours/year, the apparent power S is 660kVA. Current is 1003A. This is the rated current that can be supplied to the building at 380/220V. S √(3) V_LINE I_LINE I_LINE S / (√(3) V_LINE) 660kVA / ( √(3) * 380V) 1003A Power factor 0.8 lagging, which means at worst case the loads attached to it can have a power factor greater than 0.8. Power factor P / S. P S * pf 660kVA * 0.8 528kW The Real Power P or W loads the generator can supply are 528kW. So it can supply 5280 100W light bulbs, for example. If power factor is 1, 660kW could be supplied. There should be an electrical switchboard close to the generator, which will have labels showing how power is fed throughout the building. Everything else is specific to the device (Model, Serial, etc). Probably too much information for you, but when you are trying to understand something too much is better than too little.
