- Q: I am looking to save money on the electric/gas bill this winter and am considering a diesel generator to supply domestic power at 240 volts.Is this practical?
- nope
- Q: ANDwhat kind is it? How many times have you had to use it? How many things could you run on it? How much did you spend? Would you buy one with more power next time, or is the one you have sufficient? What types of problems have you had with running it. Do your neighbors always ask to hook up to it?
- I have a Generac 5500XL generator. It's been used on several occasions, the longest being 3 days after Hurricane Juan blew through Nova Scotia in September 2003.
- Q: HI FROM NEW ZEALAND.I HAVE A LISTER-PETTER 16 KVA DIESEL 3 PHASE GENSET WITH SINGLE PHASE SOCKET @ 240 VAC. WITH A ITALIAN ELECTRONIC DIAGNOSTICS CONTROL PANEL WITH BREAKERS ETC.WHEN RUNNING A ESAB CADDY PROFESSIONAL 140 INVERTER WELDER @130 AMPS USING 4 MM HARDFACING RODS, ON FIRST STRIKE THE GENSET CUTS OUT AND DIE.WHEN USING A COPPER WOUND TRANFORMER WELDER THE THING RUNS WELL BUT WILL NOT STOP WHEN I HIT THE KEY TO TURN OFF OR EMERGENCY STOP BUTTON.NOTE; THIS IS A STANDBY GENSET IN THAT I JUST PLUGGED IN A WELDER, THE GENSET IS NOT A DEDICATED WELDING GENERATOR.I USED OTHER DIESEL GENSETS PRIOR WITHOUT ANY PROBS.WILL ANY1 HAVE ANY CLUES? REGARDING THIS.THANKS IN ADVANCE.CHEERS CARL GIN
- Does the Esab welder have high frequency? If so the high freq. is feeding back into the generator and frying the electronics. You may need to have the generators repaired. The only way to prevent damage is to turn the high freq. off, or drive an earth ground as close to the welder as possible and you have to run a wire to your grounding clamp to this ground and the machine ground needs to go to this also. You have to get the high freq. out of the circuit as quick as possible. (I have a Hobart Champion Fabshop that is notorious for this.)
- Q: how does a generator work powerlessly. i mean like if there is a black out people cna generate energy from like a generator. well then how come a generator work without the help of anything? (NOT TALKInG About the hydropower generator, the one that spins.
- As pointed out generators convert mechanical energy into electricity. The mechanical energy is provided by an engine that uses some type of fuel like diesel or natural gas. All generators spin to produce power. well then how come a generator work without the help of anything? Backup generators do seem to magically produce electricity during a power failure Backup generators are fitted with automatic controls that handle the starting and placing of the generator onto the buildings power bus. The automatic controls are powered from the AC mains to keep a set of batteries charged. THe batteries are used at the beginning of a blackout to power the automation and start the generator. (Once the generator is running these batteries may then be recharged from the power produced by the generator or when the AC mains is re-established.) Electronic controls sense the loss of AC power and trigger a starting sequence. The generators starter is engaged to crank over the diesel or Gas engine. The controls monitor this process to ensure the engine actually starts and that an excessive amount of cranking doesn't occur. Once the engine is running and brought up to proper speed additional automatic controls disconnect the now powerless AC mains from the buildings buss and connect the Generator power to the buildings electrical panel. Based upon the size of the generator some or all of the buildings power may be supplied by the backup generator. Without the automation the process is still the same except a persone would have to perform the process of starting the gen and placing it on line. Its not difficult to do but does require some trainng. Automation performs this startup process quicker that what a humam would be likely to do.
- Q: And this person said it also all depends on what PLANT the stuff came from. No wonder the asian kids are ahead of us.
- If it's a diesel generator, why could it not run on BioDiesel? Not sure about the plant part, but provided it's not unleaded, I see no reason to not consider Bio as an option.
- Q: If a 13L big diesel engine can produce 400 hp at 1800 rpm, and a 7L diesel can produce 400 hp at 3600 rpm, but the 13L produces twice the torque, which would produce more electricity?
- The 13L would produce more electricity.The smaller generator has to work almost twice as hard to do the same job. Torque is a measure of the turning force on an object such as a bolt or a flywheel. For example, pushing or pulling the handle of a wrench connected to a nut or bolt produces a torque (turning force) that loosens or tightens the nut or bolt. Also the higher the RPM the hard the generator has to work to get to 400hp so your 13L at 3600 RPM would produce around 750 Hp
- Q: I accidentally filled my generator with diesel instead of unleaded. It already had a half a tank of unleaded so it has about half a tank of diesel. To make the full tank. Can anybody help me out please.
- That won't hurt anything, the generator just won't run well because there is too much diesel for it to burn right. Take the fuel line off of the carburetor and drain it all into a can and put new gas in, it will be just fine. You can take the stuff you drained out and put it in your car so you don't waste it, you'll never know it was there if it's just a gallon or two. It won't hurt anything. But do not do this in reverse, by putting any quantity of gas in a diesel bad news.
- Q: I have a diesel truck as well as a 25,000 watt diesel standby generator for my home. I'm curious if they will be affected should a solar flare zap us. I'm not too well versed in the whole solar storm issue.
- Most solar storms don't affect us but occasionally intense electromagnetic disturbances can knock out communications or possibly even overload power grids. I wouldn't worry too much about your diesel truck. Not too sure about your generator but it's highly unlikely to be affected.
- Q: For hydropower how much MWh can be generated with same capacity plant?. (Because plant never run for 24 hours of the day we need a factor to calculate above value)
- there are about 2000 ,working hours a year on 40 hour work week. I would guess about 200000
- Q: I want to build a diesel engine driven generator. The type of gen I have is asynchron, 400/690 V, 7,5 kW, 9,4 kVA and I was told that I need to stimulate it with capacitors (the unit is supposed to work without connection to a public netstand-aloneisland-service). Who can give me instructions how to do the el. part, size/type of capacitors etc?
- Because it lacks a separate field circuit, an induction generator cannot produce reactive power. In fact, it consumes reactive power, and an external source of reactive power must be connected to it at all times [1]. So you are right that you will need a three-phase capacitor bank at the output terminals (delta-connected). How to size the capacitors? That depends on a few things. Namely what kind of loads are going to be attached to it. I presume this is going to be an emergency generator operating alone (most induction generators are used this way nowadays). In that case, your capacitor bank will need to account for the generator consuming reactive power and the loads consuming reactive power. So, if you know what you are going to connect to the generator, figure up an estimate of the total reactive power of your loads. Then estimate how much reactive power your generator consumes (not sure how to do this; maybe estimate from your 7.5kW and 9.4kVA ratings?). Finally, to size your capacitors equate the total power consumed by gen and loads to this formula: estimated_3phase_power_consumed 3*(line-to-line_volt)^2/X where X 1/(2*pi*freq*C) Solve for C and there you go. My source indicates that the output voltage for an induction generator can vary quite a bit with varying inductive load, so bear that in mind and maybe oversize the caps a bit. Also, the types of capacitors should be able to withstand AC obviously and be rated within your expected operating temp, etc, etc. Good luck.
