Q: I recently purchased a portable generator that is 7 hp and 3050 continuous watts, i tried to calculate the efficiency as follows:743 watts 1 hp7 X 743 5201 watts, (so at 100 percent efficiency, 5201 watts is possible to produce from a 7 hp generator.)the unit produces 3050 watts, so the 5201 watts (possible watts)/3050(actually produced watts) (0.5864) or approximately 59% efficiency, this does not seem right, it should be about half that.What am i doing wrong?: First, nothing operates at 100% efficiency. You are converting angular rotation into electric power and in any conversion of power, you lose efficiency. 59% efficiency isn't that bad. Second, generators are measured at continuous power and peak power. Check your owners manual or look on the side of the generator. At peak power, you will find that the efficiency is greater.

Q: if a diesel generator(say of negligible mass) is used to power an electric car powered by an electirc motor how efficient will it be when compared to a car that uses an i.c engine thats uses diesel directly?: Direct use of the diesel engine to run the car is more efficient. With the other option, there is a chain of energy conversion each involves a loss.

Q: Details of the equipment and plant capacity are as under:Power generation plant having 02 gas generators and 01 diesel generator ( general maintenance outsourced)HVAC plant (general maintenance outsourced)Fire tube boilers one operational and one stand-by (maintenance by plant personnel)Automatic Lubricants Blending system (maintained by plant personnel)Blow molding machines (maintained by plant personnel)Injection molding machines (maintained by plant personnel)Screw Air compressors - 04 Nos (maintained by plant personnel)Fire Fighting Network including fire hydrants and monitors (maintained by plant personnel)General maintenance of 02 PE buildings and 01 RCC Office BlockAutomatic Filling machines (for small cans) (operated and maintained by plant personnel)Gear Pumps and motorsLubricants oil tank in tank farm areaMotor vehicles including 03 tank lorriesOverall maintenance of plant that is not included in above: I assume (maintained by plant personnel) means the maintenance staff doesn't do that job. Start with one person half time. Keep adding hours and personnel until the level of maintenance reaches the plateau you desire. Or go in one night and sweep the entire plant and dump the trash cans yourself and multiply the time it took you by three. Keep adding hours and personnel until the level of maintenance reaches the plateau you desire. If you want the bathrooms to sparkle and all the paint to be recent and fresh, it will take more hours than good enough.

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: avr is automatic voltage regulator for power generators: If you mean the build-in pcb of a fuel/diesel generator which build-up voltage initially and then keep it stable under any load, then read this: First you need to see your generator minimum requirements to determine specs of AVR. You will probably found a label on generator with those Information: Ex. volt (maximum excitation voltage) Ex. amp (maximum excitation amperage) Your AVR output must exceed those specs. If generator is brushless type in most cases it does. Also input voltage of AVR must be the same as output of generator (ex. 110V110V, 220V220V). If generator is triple phase then you can do the same (ex. 380V380V, 440V440V) but if generator have output in star formation then you can use node for a smaller voltage of AVR (ex. 380V220V, 440V253V). If generator work in parallel operation (usually marine main generators does) then things get complicated. In this case AVR is good to support current transformer to make generator more elastic under load fluctuations and match other generators in the same circuit.

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.

Q: Hello. we are installing a Diesel Generator for running our house. We are off grid. We are buying a Cummins 15 KVA/12KW Prime Power Generator. This generator can supply 23 Amps per phase in the standby mode with a PF of .8 With the normal set up, we can run only 3, single phase 18,000 BTU ACs, one on each phase. I read somewhere that by installing Power factor Capacitors, we can install more than one AC on each phase. Do you know anything about that? Is it an easy task or do I need to get an engineering degree for this? I'm some what comfortable with doing electrical work and can do minor calculations as well.Any help would be really appreciated.Greetings from Iran: I'm not an HVAC expert, but I am an electronics expert. the power factor caps are used to limit the huge power surge when the AC compressor kicks in. They do not give you free power or allow more load. They just smooth out the load to protect the genset. there is a saying in the AC world about ELI the ICE man. in an inductive circuit voltage leads current, in a capcitive circuit, current leads voltage. the compressor is inductive, so you add capacitance to adjust the power factor.

Q: I have two deisel engines and two tank feeds, how can I connect the genset (4KVA) . I am conerned when the engines are idling or even running they will start the genset. I do not want to put an extra tank.Thank you: If your tank has another port on it for a fuel line that is where you hook up. If not go to the supply line at the tank and put in a T fitting and then a shut off valve for each engine. Run the supply line to the generator from that T. You will also need a return line from the generator that you can T into at the return line from the engine at the tank. Many people that convert from gas to diesels run into these same problems. Often a fitting is made up that is put in the fuel fill line to allow for the return line. The generator supply and return lines will be smaller then the engine fuel lines. Running the engines will not cause the generator to start.

Q: I want to be able to plug my APC Smart-UPS RT 8000VA 208V into a diesel generator when our power will be down for an extended period of time. The max OUTPUT of the APC unit is 6400w. Does that mean I need at least a 6400w Generator?: yes, plus extra for loses and to charge the battery. I'd get a 10kW unit, at least. But that is a lot of power, do you actually use all of that, or is the UPS oversized? In that case you can reduce the size of the generator. .

Q: i have a plan to supply electric power supply to a colony of around 250 houses each have a load of approximately : 3 x1.5 ton air conditioners and all the other stuff of household use. voltage required is 400v 3 phase or 240 volt single phase. my question is if some one can please calculate the requirement of load for the above requirement and what size of generator is required for this load. thanks: With that large a system, you should get a quote from professionals. You need better numbers on power usage, both average and peak. And the pros can help with that. See if you can get a sample of 10 electric power bills and use that as an average to calculate the average power for all 250. Peak is difficult. They each have 4.5 ton worth AC? must be a hot climate. You can use 1.2 kW per ton, so that is 5.4 kW per house or 1.4 MW total just for the ACs Is there electric stoves, hot water, etc? that could double the above number. So we are up to perhaps 3 MW already. At that level, you probably need a higher voltage system, perhaps a 6 kV distribution system. That costs money, plus all the transformers, one per 2-4 house, plus all the underground digging. Assuming you want this underground, not on poles. Again, contact a company that does this, such as Siemens, Bosch, GE, they would be happy to give you a good quote. edit: when you look at the ratio of peak power to average power, you will see a large number, as high as 10. that means you could require a (eg) 3 MW generator although the average power is only 0.3 MW. That means the efficiency is low and the costa are high. That is why large power distribution systems are much better, as the peaks are not nearly as high, and also power companies have special units that are usually offline and come online to handle the peaks.
