Q:45 kva Perkins diesel generator cranks?
Diesel cranks but doesn't start. All that's left is the fuel system. Is there a pre-heat unit? Is it working? Pressure at the injectors?
Q:Does more Power Demand burn more fuel?
Same power, same usage (with very slight increased wiring losses with 10 bulbs) 1 KWH is 1 KWH no matter how it is used.
Q:What are the functions of frequency meter and also its safety precautions and connections? thank you?
The frequency meter is used for measuring the frequency of an alternator or other equipments like variable frequency drives. It should be connected between two lines of a unit. Check for its voltage rating. The meter should be rated the same as the voltage rating of the line being measured. It could be used also for vhf and uhf frequency, digital or analog. So depending on your application, you have to specify its frequency range and voltage rating.
Q:What is the ideal economical maintenance staff required in Lubricants Maufacturing Plant?
If approached and done wisely, the screwing procedure (tightly or otherwise) might want to no longer require extra lubricant! If extra lubricant is needed some step replaced into both skipped or done at a below sufficient factor .
Q:Any experienced Electrical Engineers out there?
Is it too late to switch to a 240 volt single phase generator of the same capacity? This would have a 60 amp capability and would handle the surges with no trouble. I don't see how a capacitor will help. If you are stuck with the 3 phase generator, perhaps you can switch the ACs for ones with 3 phase motors. That will spread the surge over the 3 phases. There are also soft-start ACs .
Q:What are the procedure of start up of emergency AC Generator?
Is this generator going to be used in a location which is normally served by grid power. If so is it proposed to use the distribution system normally used when on the grid? If the answer to these questions is yes. The first step is to isolate the normal energy source. This has two purposes. a) to protect your equipment when power is restored and b) to protect people and equipment working on the external circuit. Once this is isolated wire the generator into the circuit (closing isolating switch if hard wired). Start the generator using normal procedures with minimal load in place. Slowly increase load until desired effect is achieved. When external power is returned. Slowly reduce load and isolate generator. Restore normal grid connection. Shut off generator.
Q:Couple questions about backup generators for buildings?
Back up generators are kept as stand bye.In hospitals and other important places they take start immediately when voltage drops in the main. They Run with petrol or diesel oil or other fuels/
Q:What are the materials used in diesel generators
Diesel generator consists of diesel engine and generator
Q:Bus generator problems!! Any Advise for replacement?
You don't say what the generator problems are. It may be undersized for the AC units you are trying to run plus other things you are trying to run. The AC unit may require all of the generator's capacity for about 2 seconds to start. So if one AC is running, there may not be enough capacity to start the second AC unit. What other things are you running off the generator at the same time? The 6,500 watt generator can only supply a maximum of 27 amps out of the 240 volt outlet or 15 amps out of each of the 120 volt outlets or any combination that does not exceed the 6,500 watt capacity of the generator. A diesel engine has nothing to do with the capacity of the generator. Diesel engines are used on larger capacity generators or continuous duty generator sets. The generator itself doesn't care what type of engine is spinning the rotor. Will the generator run just one of the units? If it does, then my thoughts are the generator doesn't have the capacity to run the loads you have.
Q:What rating is my generator really? (Industrial)?
Treat all of the figures as maximum rated outputs. The maximum power it can delivery is 520kW, that is why it says 520kW. 640kVA and power factor 0.8 should not be be exceeded either but if your load is pf1 then the 520kW will take precedence. No offence but anyone who can't interpret these numbers shouldn't really be testing equipment of this power.
