3. INSPECTION AND TEST
1 GENERAL
1.1 Each engine shall be tested at manufacturer’s workshop to certify the engine output and fuel consumption in accordance with the site operating condition specified by purchaser on the specification datasheet.
1.2 All relevant information drawings pertinent to the testing and test procedure shall be transmitted to the purchaser in advance of the test date notification.
1.3 The purchaser shall call for additional testing if test results are unsatisfactory or marginal. Any equipment rejected shall be repaired or replaced to the purchaser’s satisfaction and tests shall be repeated.
1.4 Any unsatisfactory material, equipment, installation, or workmanship shall be replaced or repaired to the purchasers satisfaction at the manufacturers cost.
1.5 The engine and generator shall be tested individually in accordance with relevant standards specified above.
1.6 The completed and individually tested engine and generator shall be assembled onto the base plate with all auxiliaries, instruments and controls for a complete test of the generator set.
- Q:I have noticed that our kilowatthour meter reads backwards when I use some electrical appliances, please explain why. plgperera.
- are you sure u dont have a diesel generator that sells el. energy back to the grid? jk Is this first time you look at the meter? If so take a look again, should be ok.
- Q:I have a (2306A-E14TAG3) PERKINS diesel engine electric generator, every two hours it turns off by itself. The generator room is well ventilated, opened from all sides, while the exhaust is free for atmosphere without any extensions from the muffler.- 66% used as part load.- Note that this generator is a new generator. ambient temperature is almost 30 degrees celcius, humidity65%.Please help me with this issue, because every two hourse i used to cool the radiator from outside by water! I appreciate your help
- REASONS FOR PERKINS GENERATORS TO SHUT DOWN (according to Ehow): 1. Not putting out correct voltage (too high or too low). 2. Wrong frequency 3. Wrong speed 4. Wrong oil pressure (too high or too low). ///////// Other sources of failure: High current, battery won't charge, speed sensor not working,
- Q:also is it probability that will damage my computer or UPS
- Depending on where you live, your main power may occasionally be supplied by a large diesel generator. During power outages I use a 5500 watt generator to supply power to my home. The computer is on backup power and I have never had a problem. There is absolutely no reason for concern if you have a good quality generator that works properly. If your generator supplies a stable output voltage it will work fine. However if your generator operates near it maximum load and the output voltage varies in frequency and voltage there is a possibility of damage to equipment connected. A UPS may assist, but unless the generator is perfect the UPS will switch to battery power. After a short time the battery will run down and the computer shut off.
- Q:i am having a electrical paper in my semester. I want to know about the design of a electrical generator
- Torque is not the right question to ask in this problem! First define the generator output in terms of watts. Assume an efficiency of 0.8 for the generator and define the Input of the generator (In Out / 0.8). This is the output of your motor (assuming some diesel/petrol). Torque is expressed as N/m (force x radius) and is part of the electric generator specs. See there to get the equivalence. Usually, the motor power is also 0.8 efficient, so the motor power should be W / (0.8*0.8) and that will give you the right ratio.
- Q:Design the logic circuit for starting an emergency diesel generator. For the generator to start, the generator must be disconnected from the bus, there must be sufficient start air pressure, and the fuel tank must indicate there is oil. When these conditions are met, then the diesel may be started. Presume there are senors to determine these values.
- This is just an and gate function. When the outputs of all the sensors are true and a start command is present, the output of the gate will go high to allow the engine to start.
- Q:If the electrical grid fails and takes years to re-establish, how will the plants cool down?
- If they are shut down and there is no grid power, then they would use diesel generators to run the cooling systems, the generator would need refueling every eight hours. If they are operational, they produce more than enough power for the cooling system. A conventional nuclear power plant is at it's most dangerous when shut down which is ironic since most safety protocols demanded of them requires shutting them down whenever there is a slight risk such as what happened at Fukishima, had Fukishima been left on, there would not have been a problem. You could bet that even if the entire grid may take years to rebuild, the nuclear power plants, hospitals and even grocery stores would have priority and would have power very quickly, a grid doesn't have to be completely repaired for portions of it to work. Solar storms are really not a civilization ending threat, merely an inconvenience as it might take some time for the entire grid to be operational again but that does not mean portions of it wouldn't be operational sooner as in days. Of course, conventional solid fuel rod nuclear technology were developed for expediency in producing weapons grade plutonium and the proprietary fuel rods allowed the manufacturers to direct the economic benefits to themselves much as printer manufacturers do with inkjet cartridges. A competing technology called liquid flouride thorium reactors could not melt down, could not explode, could not leak, shuts down safely if cooling power is lost, stays shutdown safely without power, and consumes existing nuclear waste reducing the nuclear wastes to a small amount that only needs to be stored for 350 years instead of the current 30,000 years. The military had no need for it, the government didn't want it because it did not employ an army of technicians, the reactor manufacturers didn't want it as it did not have proprietary nuclear fuel rods.
- 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?
- It sounds like a really bad idea. Not just noise-wise, but storing petrol or diesel in your apartment is a significant fire risk and possibly breach of your tenancy/lease agreement or giving an insurance company a let-out in the event of fire. Are you sure you don't mean 700va ? this is about the smallest, quietest generator.
- Q:I heard about the reactor and could someone tell me the story and what could happen thx.
- The Nukelier chandelier has probably been reactivated to supply the needed power to the millions that will shrivel up because of the Nukelier fallout. Let 'em go happy!
- Q:I heard about the diesel electric concept from a friend and he didn't have a lot of details, but from what he knew it sounded really interesting. I was wondering if someone could give me some details on to what this new technology really is, and how it works. Thanks!

- Q:Explain the operation,advantages and disadvantages of diesel power plant?
- I am not sure what you are really asking about the operation of a diesel generator. You start the engine and connect the electrical load to the generator buss. If you are connecting to a grid or existing power system then you need to match the frequency of the grid. As to advantages and disadvantages, you need to state what you want to compare it to and how large the generator or system is.
