What is a turbine exciter?
A turbine exciter is a device used in power generation systems to supply the necessary excitation current to the rotor of a synchronous generator, which is typically driven by a turbine. This excitation current creates a magnetic field necessary for the generator to produce electricity. Exciters can be static (using power electronics) or rotary (mechanically coupled to the generator), and they play a crucial role in maintaining voltage stability and controlling the output of the generator. Proper functioning of the exciter is essential for efficient and reliable operation of power plants.
Where can a DC exciter be found?
It can be found on an electrical generator set. It is used to supply the DC voltage for the field coils.
What is exciter in electrical?
An exciter in electrical engineering refers to a device that provides the necessary excitation current to the field winding of a synchronous machine, such as a generator. This excitation current is essential for establishing the magnetic field required for the generator to produce electrical power. Exciters can be either rotating (mounted on the same shaft as the generator) or static (using solid-state technology), and they play a critical role in regulating the output voltage and stability of the generator.
What is a exciter generator?
its creates the magnetic field trough the electricity,which we called exciter for it.we send some electric shocks to the field coils,then it will magnetized the stater of the generator. When Diesel or petrol engine rotates the rotter of the generator, EXCITED stater act as a magnet. Depend on alternator`s design,rotter or stater one always EXITED to be a magnet. When engine turns the Alternator against the magnetic field,electricity is produced.
Why the pilot exciter having high frequency in electrical generator?
I'm no expert but I believe the high frequency is due to the number of poles (North-South) of the pilot exciter. The frequency of a generator is directly link to its speed and the number of poles. Most generators will run at 1800RPM and will have 4 poles to achieve 60Hz. The pilot exciter being on the same shaft will also run at 1800 rpm but will probably have more then two poles. finding the formula for frequency of a generator should help you in answering your question. The next question should be why would you build a pilot exciter with multiple poles and a high frequency? The output of the pilot exciter is going to be rectified to DC so it would make sense to do it with a high frequency and get a smoother DC signal out of the rectifier.
What is the function of exciter rotor and stator in Generator Operation?
In the operation of a standard generator, the exciter rotor and stator provide DC-type energy to an AC-type supply. This allows the exciter to maintain a constant DC source.
What is a exciter used for and why?
exciter is a component in a electrical generator and or the low power rf stages of a radio transmitter
How generator exciter works?
Generator Exciter is a new way for people to generate serial keys for pirated software for various companies. This is well known as something called a "keygen".
What is the use of permanent magnet generator in exciter?
A permanent magnet generator in an exciter is used to provide a stable source of excitation power to the main generator. This allows the main generator to maintain voltage output and stability during operation, ensuring efficient power generation.

What is the excitation of the generator?
The rotor must have a magnetic field in order to generator voltage in stator winding. The exciter circuit generates this DC filed in the rotor.

How to make a light flashing generator work with a cell battery?
If a generator turns off or will not start up due to loss of magnetism, it is possible to use a 12 volt battery to make it work. You have to remove the exciter fields, measure the exciter field resistance, connect the F+ to the positive end of the battery, hold the F- lead near the insulated part of the lead wire and place it on the negative end of the battery for 5 to 10 seconds, then reconnect F+ and F- to the regulator.?æ
What is the exciter voltage needs to test the generator?
Because the voltage is fixed (within allowable limits) whereas the current varies according to load.
