• Used to provide the highest mA settings at the
shortest time possible.
– The operator selects mAs setting
– The computer automatically calibrates the time of
exposure (allowing consistently shorter exposures)
– The mA is therefore controlled by the falling-load
generator.
– The mA starts at the highest possible setting and
“falls” throughout the exposure.
• This causes the kV to fluctuate slightly throughout
exposure.
• Can shorten tube life due to constant use of high mA

Can DC series generator start on no load?
yes.it is possible to start dc series generator on no load condition
How does a generator adjust to the load?

What is meant by load in diesel generators?
Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.
What happens if the synchronous motor exceeds its load capacity?
If load on a generator is greater than the generator can provide, the generator will begin to slow down. If it slows down too much, it will lose synchronism.
What is needed to perform a no-load bench test?
A bench and no load! Whatever you are testing has no load. It might be a generator or a motor for example. If a motor it wouldn't be connected to anything. If a generator it would have nothing plugged in.
How is a Load applied to a ac generator?
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
What is the load rejection and load pick-up in the power generation?
Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection. Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.
How to compute the minimum load of 16 MW generator?
A generator, rated at 16 MW, should be able to continuously supply a load of 16 MW. You don't need to compute its 'minimum load', because the minimum load will be zero watts! In other words, you can run the generator with no load whatsoever if you wish to waste fuel.The point is that the power supplied by a generator is determined by the load, NOT by the generator itself -so it is important that the generator is capable of supplying the maximum load applied to it. A generator's 'rated power output' simply tells us the maximum load it is capable of supplying.
Can DC series generator start on no load?
yes.it is possible to start dc series generator on no load condition
How does the load affect voltage output of a series generator?
In a series generator, as load is added, output voltage increases.
What is the basis of a generator load?
The load on a generator is a general word for whatever device is connected to it to use the power that is being generated.

What is meant by load in diesel generators?
Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.
Why electric generator drop the load?
Too much load for the generator, the generator began to under speed / overspeed, the governor / part of the generator went into failure, the generator capability was not up to the requirements placed by the system (needing to push out/pull in too many VARs), etc. there are many reasons for a generator to drop a load. Because a load dropped, this does not infer that the generator was the cause either (fault on the system, system instability limits reached, system protection tripped - non-generator related protection).
How it is getting current from generator?
To draw current from a generator, you need to connect a load to it.
What could be the cause of overspeed in a diesel generator?
The causes of over loading in generator comes from the action of applying more load that the generator is rated for. An example using a 5000 watt generator and a connected load of 6000 watts.
How long can a 3000 watt generator power a TV?
A 3000 watt generator can run from 8 to 20 hours on a single tank of fuel, depending on how heavy the load is. This type of generator employs an Eco system where if the load is shut off, the generator slows down to an idle state and stays there until the load is sensed again. On re sensing the load the generator speeds up to its rated output. Since a TV is on the very light end of the load, the generator should remain operating on the top end of the hours scale.
