Does load affects fuel consumption per hour of a diesel generator?
If the generator is to maintain the same rpm and power output, then a heavier load will increase the diesel consumption. The revolutions per minute the generator runs will increase as the load increases, thereby resulting in an increase in diesel consumption to maintain the high rpm. A Generator has a governor which attempts to maintain frequency at 60 Hz for North America. For the generator to increase the power output at the same frequency, the governor will increase the fuel and air to the engine. The fuel consumption will not be linear because of the curves associated with the particular engine. The fuel to KWH is know as the heat rate curve for the generator.
How do you step down frequency and voltage from an AC generator?
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
How do you increase the frequency of Alternating Current?
There are two ways. If you want to increase the frequency by a huge amount and you want to do it on a permanent basis, install more magnets. An alternator that has one pair of field magnets and that turns at 3600rpm will generate 60-hertz electricity. If you put two pair of field magnets in it and turn it 3600rpm, it will generate 120-hertz electricity, and so on and so forth. (The other side of that is, if you want a certain frequency of electricity, the more pairs of magnets you install the slower the alternator has to turn. Install four pair of magnets in the generator, and you only need to run the engine at 900rpm--which makes it much quieter, a big advantage if the generator belongs to the army.) If you just need to adjust it a little, simply rev up the engine. If you have a generator that makes 60hz power at 3600rpm, accelerating the generator to 3660rpm will cause it to make 61hz electricity.
Why a given generator frequency is dictated by the size of the magnetic flux?
A generator's frequency is dictated by the power system frequency, and the number of poles in the generator. For 60 Hz power and a generator designed with two poles, the generator must turn at 3600RMPs (60 Hz * 60 seconds / minute). The magnetic flux is what induces the current in on the output winding. Spinning a synchronous generator faster or slower is not done to control the magnetic flux. The field winding voltage is varied to control this, and in turn control the output of the generator.
How do you modify the frequency of an AC generator?
You change the speed of rotation.
How do you troubleshoot the voltage flickering of FG WILSON diesel generator?
If you can see the lights flickering then there is a good chance that the frequency of the generator is low. To increase the frequency just increase the speed of the generator. On bigger diesel engines there is a knurled knob, located on the fuel rack, that can be turned up to increase the speed. If the unit has a frequency meter check to see if it is on 60 or 50 Hz depending on what country you live in. Don't depend on the frequency meter as they are not always accurate. Use a test meter that has a frequency scale and set the generator with the meters reading.
Does load affects fuel consumption per hour of a diesel generator?
If the generator is to maintain the same rpm and power output, then a heavier load will increase the diesel consumption. The revolutions per minute the generator runs will increase as the load increases, thereby resulting in an increase in diesel consumption to maintain the high rpm.

Use of low frequency clock generator?
How to make Low frequency clock generator using ANAD gates?
Why must the oncoming generator on a power system be parralleled at a higher frequency than that of the running system?
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
How you can increase the generator terminal voltage when synchronise with other generators?
The whole idea of synchronization is that you DON'T change the voltage (or frequency) from the other generators.
What is baud rate generator?
baud rate generator is a frequency divider
How do you step down frequency and voltage from an AC generator?

What is the significance of the rotation of a generator?
The significance factor of the rotation of a generator is, that this rotation is what governs the frequency output of the generator.
What is the purpose for generator synchronising?
The purpose for generator synchronizing is to match the speed and frequency.
How 50Hz frequency is selected for a generator design?
Frequency is a function of engine speed and the number of poles in the generator end. For instance, a speed of 1500 RPM turning a four-pole generator will produce 50 hz. The formula is: Frequency = (poles/2) * (RPM/60) From the formula, you can see that the same frequency would be produced by a two-pole generator spinning at 3000 RPM.
How do you step the frequency from 50hz to 60hz?
The frequency of a grid system is set by the rotation of the generating equipment. If you have a small generator, the frequency can be increased by increasing the speed in revolutions per minute of the engine driving the generator.
When wavelength decreases does the frequency increase or decrease?
The wavelength is inverse to the frequency, meaning the frequency in this case will increase.
