Q:generator is 730 kva.to check its working time, consumed diesel, i purchased a software.but i wish to know how i connect it with computer? is it safe? any precaution? any electric wiring diagram? is it safe etc. i want to use thumb scaneer as start and stop switch.

It really depends on how old the generator is. In the last 15 years or so the engine/generator controllers came with some of the things you seek. It really depends on the manufacture, (onan, kohler, generac,cat etc.) If your generator control panel is of a digital display you MAY have the capability. If it has dials and guages you probably do not. It can be retro-fit with new generation controllers that will give you what you seek. It would be expensive though,

Q:Diesel generator is generating power, how is generating, i need step by step, In self excitation how the alternator generates powerin permanent magnet alternator how the power is generated

magnets move very fast above coils of copper wire beneath it (the coils of copper wire are all attached together and the magnets are moved by a small amount of dc energy) and the current the alternators give off is ac

Q:i am going to buy a second hand generator which is 108kva diesel enginehow can i test it so i know it starts but also is capable of running around 80-100kvai want to make sure it is strong and still working and not that it just startsplease help thankssam

You need to load test it and operate it to test both the power output of the diesel, and the condition of the generator.See if you can rent the use of a salt box to load test the generator.or see if the seller will allow you to hook it up to your equipment at your place and see if it will carry the load under real world test conditions. Note, a marine electrical shop,or motor rewind facility should have a salt box. Call and ask them

Q:I recently had solar Pannels installed. The panels generate enough electricity to power my house during the day. I use a 20kw silent diesel generator to power my house at night. I really hate my power provider PGE. If i tell them to shut off my power, Will they remove that tacky smart meter from my property?

You can have them remove it.

Q:I recently seperated the generator from the engine and replaced the rear main oil seal on the engine the electric generator was only moved back about 16-18 inches to access rear main seal. job went well with no problems after completeing job I turned down rpms to about 1000 rpm It was put back in service They use it to power up refer containers from the harbor. the next day I check it and they had turned up rpms to ??? as fast as it would run and 12 refer units running off it oh it's 480 volt well it ran for a week non stop and broke down and of corse it was my fault all i did was unbolt drive plate on front of rotor from flywheel of engine .est to repair is 6,000 could this be my fault after it ran for a week or caused from hi rpms and heat related possibley

A little more information would be helpful as to the size and model of generator. Is it possible the repair shop could give you more detailed explanation as to exactly what they believe happened? Is this a single bearing or two bearing generator? If it has only one bearing and the shaft is supported by the engine flywheel on the engine end, then the postion and shimming of the engine and generator may be critical to keep the rotor centered between the stator poles. These clearances are very small and they could have been rubbing if not aligned. On small single bearing types, the housings are made to fit together in perfect alignment, and can not be misaligned to avoid this problem. On larger units, this matched housing arrangement may not be possible. A generator with a bearing at each end of it's shaft is less likely to have this problem of rotor alingment, It would have a problem with coupling or bearing failures if not properly aligned with the engine.

Q:I need these values for 400 KVa and 150 KVa plants in order to run an air pollution computer simulation. Thanks!. Volumetric flow is not useful for me,because i don't have any information about flow areas or diameters.

This is a difficult question to answer accurately. The velocity of the exhaust gas is highly dependent on the size of the exhaust pipe. A smaller exhaust pipe, a much higher velocity --- a larger exhaust pipe, a much slower exhaust gas velocity. A 2 exhaust pipe would have about 2.25 times the velocity of a 3 pipe. The exhaust velocity is highly dependent as well on the RPM of the generator. Double the RPM, and there is much higher pressure, and much higher exhaust gas velocity. An attached article mentions that the exhaust velocity in some unspecified gasoline powered car --- and at some unspecified RPM --- is about 240 to 260 feet per second. autolounge /tech/exhaust.html

Q:An electrical power system consists of identical diesel generators, each generator. Has a constant failure rate of 0.5 per year. Calculate the reliability of the following arrangement-three months after the initial commissioning date. 1. Only one generator operating. 2. Only generator operating, one generator standby. 3. One generator operating, two generators standby.

0.5 failure per year would mean 1 failure per 2 years. Keeping the generator off for 2 years is no good, it may not start. It is best to operate the machines at least once every few months for some length of time. The longest time to failure is usually achieved by sharing the load and operating all equipment simultaneously. This method is very application dependant! Hope this properly answers your question

Q:I been thinking, and it seems to me our future vehicles would be best suited with a small 1~ liter diesel engine turning a generator to power 4 electric motors at the wheels of the car/truck, just like locomotives use. Advantages would be significantly increased fuel economy, AWD, no transmission and axle weight(offset by weight of batteries, longer lasting diesel engine, easier and cheaper to repair due to small engine size, fewer moving parts, and decreased complexity, regenerative braking, significantly reduced emmissions, less noise, no idling when not moving.Seems the advantages would vastly outweigh the disadvantagesDoes anyone build such a vehicle?

Hybrids will be replaced with electrical cars.

Q:I live 30 miles east of Seattle in an area that is frequently without power. Up until this year the outages were less than 48 hours but this year we have had repeated outages, one of which lasted 6 days after a stronger than usual windstorm. I had to scramble to find somewhere else to be. I lost several days of work, all the food in my refridgerator and freezer. At what point does it make sense to just install a standby generator?

I decided to have a portable generator with manual transfer panel while my new house was being built. It uses a deep well for water, and without electricity we can't even flush a toilet!

Q:how is the diesel power transmitted to the traction wheels in a diesel locomotive

Diesel hydraulic transmission was used a great deal in Germany in the 50s and 60s and may still do (see link to Voith) Also the Italians are using them - Trenitalia took delivery of 25 in 2000. British Railways (Western Region), which still thought of itself as the Great Western Railway in the late 50s and early 60s ordered main line diesel-hydraulic locos from Germany, or using German transmission (Westerns, Warships, and Class 35) when other regions were ordering diesel-electric locos. The Railway Gazette reports that the diesel-electric v diesel-hydraulic 'battle' is to recommence. Hydraulic transmission is akin to, but very different in detail to, an automatic transmission on a car. The last link tells you all you need to know.
