Advantages and disadvatages of a self excited induction generator?
The main disadvantage should be obvious - when the output voltage of the generator is used to provide field current to the generator....what happens if the output voltage sags? If the output voltage becomes depressed, the output power of the generator is compromised (becomes less and less), this in turn can cause the output to become more depressed, leading to an incrementally decreasing output capability. The main advantage is cost savings.
What is the excitation system in a generator used for?
The excitation system is used to control the excitation of the rotating field in the armature. By increasing the armature current, it in turn increases the magnetic flux in the armature coil. This has the effect of increasing the voltage output of the generator. By lowering the armature current this in turn lowers the generator output voltage. The generator's voltage regulator automatically adjusts the output voltage continuously as the applied load on the generator changes.
What happens to the output in terms of real power of a generator when you change the voltage and frequency say from 220v 50Hz to 110v 60Hz?
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.
What type of voltage is the output at the bat terminal of the ac generator?
dc
What does the voltage regulator do on a generator?
A voltage regulator controls the output voltage of a generator. This ensures only the specified ÊvoltageÊis supplied thus preventing damage to the circuit and other electrical appliances.Ê
What limits the output of an electrical generator?
The amount of voltage of an electrical generator will determine the limit of the output of energy. If the voltage is too high, it can burst the pipes causing it to shut down.
How does the load affect voltage output of a series generator?
In a series generator, the voltage output is directly affected by the load. As the load increases, the voltage output decreases due to increased voltage drops across the internal resistance of the generator. Conversely, reducing the load will result in an increase in the voltage output.
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
How does a voltage regulator regulate the voltage output of an ac generator?
Generator output is controlled by voltage feedback to the voltage regulator which senses voltage drop or rise and regulates the current being sent to the armature. This rise and fall of the armature current governs the generators output voltage.
The relationship of the strengths of the two fields in a generator determines the amount of what?
The relationship of the strengths of the two fields in a generator determines the amount of electrical output or power generated by the generator. When the magnetic fields are strong and properly aligned, it results in a higher voltage output and more efficient power generation.
How do you raise voltage in generator?
Increasing the field current will boost the generator output voltage, assuming the governor doesn't limit.

Is it possible to turn a 2.7kva Honda generator into a welder generator?
No, the output voltage is too high.
What is a reversing relay?
A reverse current relay prevents a generator from discharging the battery when generator output is less than battery voltage. When generator output is greater than battery voltage, the reverse current relay closes and connects generator to electrical bus.
What type of voltage is the output at the bat terminal of the ac generator?
dc
