Q:can DG's be used as a backup for single phase and three phase ac?

Yes but they need to match the power source they are replacing.

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.

One other consideration for your generator is the natural gas has less power in the range of 25% If you need 7.5 KW and it is natural gas then the generator needs to be a 10KW unit. Diesel is quite reliable but storage of fuel is a concern, for petrol also. I suggest you contact a local electrical contractor who specializes in home generator installations. 25 KW is about the smallest for your needs. 40 is probably a better choice. All in all they are not cheap.

Q:has there been any long term tests on the effects on the engine from running it on hydrogen produced from a hydrogen generator and your ordinary gasoline/Diesel?also has anyone attempted to hook a hydrogen/H2O/Brown's gas generator up to a actual diesel generator like wisperwatt or any kind of diesel generator?any help would be great thanks!

Long term or short term is that is doesn't work. It's a con and I can prove it. I've been posting here a long time and have posted why it won't and can't work and the HHO people have NEVER not once shown where I'm wrong, I post all my numbers shown all my math, I've even show where I get my numbers. I've even assumed that HHO works and used THEIR numbers and it still doesn't work out. Sorry but there's no free lunch. Post an edit if you want to see why it won't work using their numbers and assuming it works.

Q:hiam in the process of purchasing a flat.under the electrical specifications, the builder has specifid the following. please explain me what does it mean by3 phase power supply with automatic change over switch and what does it mean by RMU Transformer with Advanced Features

This electrical specification describes some aspects of the electrical distribution system for a block of flats (apartment building in USA terms). A 3 phase power supply is 3 live wires and a neutral with 400 volts or so between any two live wires and 230 volts or so between any live wire and the neutral. Each flat would be connected to one live wire and neutral. A change over switch is a switch that can switch the load from one power source to another. It could switch between two mains connections from the power company or it could switch between the power company mains and a standby diesel generator set. An RMU transformer is a ring main unit transformer. The transformer would be the step down or substation transformer from the transmission line voltage to the 400 volt level. There would probably be one transformer for all of the flats, possibly two if there are two mains connections from the power company. The RMU designation indicates that the transformer includes additional components such as the change over switch and main circuit breaker as a single piece of equipment. Advanced features might include such things as transformer temperature monitoring, load monitoring, and remote indication provisions. Unless the features are enumerated, it isn't a particularly useful description. It may or may not include features in addition to the minimum required by government regulations. If you are purchasing only an individual flat, this might offer some assurance that the electrical system is modern and reliable, but it is a very poor description to offer prospective purchasers of individual flats.

Q:What is the maximum power of a diesel generator

The diesel is ignited and the mixture is heated and the volume is rapidly expanding.

Q:I am looking to run a 1200watt electrical generator using Hydrogen gas versus using Gasoline, Propane or Diesel. If anyone knows even where I can start looking towards steps or plans for something like this?

Um, can I ask you one question. why? Internal combustion engines can run off of hydrogen, sure, that's a no-brainer. But can I ask where you have an unlimited supply of hydrogen available to you, such that it's so much cheaper to use that it's worth it to make a very complicated expensive modification such as this? And why not just directly convert it into electricity with a fuel cell? It's far more efficient, lower maintenance, and sooooo quiet you could hear a mouse fart right next to it. Nice pie in the sky, but currently quite impractical.

Q:I have a new Onan 10k diesel generator engine and an old isuzu pickup truck not worth engine replacement cost. Can this small diesel be adapted to fit the manual transmission?

This conflict is a waste of money: the only thank you to win is to kill, kill and kill untill there is not any one left to combat. do no longer look at human beings, basically overrun territory and lay waste to each physique there. we are unlikely to try this. we are basically going to maintain the stare-down till our leaders have the experience to ultimately crap or get off the stool. there is not any longer something to assert clever adequate to get each physique to cooperate peacefully. shall we advance extra advantageous skill technology and remodel to run extra issues with electricity, yet which will additionally come at a value. persons isn't polluting as lots the place they're each and each, however the extra load on skill agencies will throw out extra warmth and waste making electricity for use. That shifts the subject from one set to a distinctive. image voltaic and wind skill is cleanser. The sunlight shines each now and then and the wind blows each now and then, yet batteries will would desire to be a heck of so lots extra advantageous than they're to paintings as much as we choose them to run autos, trains, ships and autos. overlook flying with them. Hydrogen fuelcells will would desire to be fed via extra advantageous supplies of hydrogen besides, for a similar reason. There are ruin-thoughs slowly recovering this. 40 years in the past a capacitor that would desire to hold the skill mandatory to run a gadget any functional quantity of time would would desire to be bigger than a trashcan- now this is held interior the palm of your hand. It costs up speedy and discharges no longer so speedy. this continues to be no longer stable adequate yet. there is lots paintings to do.

Q:can they be quiet? I was thinking about buying one sense we seem to have an outage every winter. Just wouldn't want to have an extremely loud generator running disturbing the neighbors

not less than 50dbrunning up to 80db.very rough figures. If you have the money to spend they can be pretty quiet these days. And you can silence them more, even bury them if you do it right.

Q:I have 1500 kw load,i want install on Diesel Generator.What should be rating?

Well, unless you're supplying a purely resistive load (nothing but filament lamps and radiant heaters -- no motors, transformers, switched-mode supplies or fluorescent lamps), you generally need a generator rated for about 1.2 to 1.5 times as many kVA as you have kilowatts. So in your case, a couple of megaVA.

Q:for a diesel generator of about 113 HP. What is the typical exhaust temperature?

i ve worked on a 440kw engine as a general rule the exhaust temperatures are never let to go in excess of 400 degrees. normal exhaust temperature at 300 kw was 350 deg celsius.
