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 else can I help you with?
What is the frequency produced by a 4-pole generator rotating at 3600 rpm?
f=P*N/120 f=Frequency in Hz P= No. of Poles N=Rotor Speed in Revolution per minute(rpm) for P=4 and N=3600, f comes out to be 120 Hz. So frequency of voltage produced is 120 Hz. But this is not practical. Generally 4-Pole generator has N=1500rpm(for 50 Hz) or 1800rpm for 60 Hz. Two pole generator can have N=3600rpm(f=60Hz). The most practical situation is generator having N=3600Hz with 2 Poles. Hope It will be helpful!!!
What is the gereral references difference between ac and dc?
AC is mainly having frequency i.e., cycles per second.as the name suggest that it is alternating current DC is not having any cycles so, it is not having frequency
Is there any physical difference between an AC induction motor and an alternator?
This from the "Induction motor" article in Wikipedia: "In principle, any AC electrical generator can be called an alternator." The only difference between an AC motor and an AC generator is whether one has electrical energy put in to get mechanical energy out, or whether one has mechanical energy put in to get electrical energy out. That means the answer to your question is basically, "There is no physical difference between an AC motor and an alternator." The unit in question can be used in either way, and assumes a name based on which way it is used.
What do you mean by electrical resonance?
This is one of the important process in communications. This is the condition at which the gain is high,because the inductive and capacitive reactances of the system equals each other and gets cancelled.
A digital circuit can be corrupted by electrical noise having a value of?
1 volt
When a generator is running and if no electrical load is attached to it where do the electrical energy generated go to?
If no electrical load is attached to a running generator, the electrical energy generated typically backs up onto the grid or remains within the generator's internal electrical system. It is important to have a load connected to a generator to ensure efficient and proper functioning.
Using a 741 op amp how do you find the resistors values having a frequency of 1khz to obtain a sawtooth generator wave?
What kind of question is that. What resistors, what circuit are you talking about?
What is the cause of an amplifier having garbled sound?
it is spoil The frequency of the unwanted electrical signals mismatch with the sound and heard as "Noise" - a garbled form of sound.

What is the definition of diesel generator?
Diesel generator are generator that uses diesel. having the ability to withstand corrosive particles in fuel(diesel).
Why am I having problems with my dish signals after a generator starts?
The generator is producing electrical interference. If the generator is powering the satellite it might be the generator output is too 'dirty' (spikey or distorted output) or the generator is on it's minimum, or maximum, load limit. The main causes of random interference from a generator are the covers being left off or open and bad earthing. Where possible run power leads perpendicular to signal leads. Where it is not possible make sure there is good separation between power and signal leads. Confirm the integrity of coaxial shielding.
Doppler effect with two people moving to each other?
In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.
Describe the steps involved in converting hydro energy into electrical energy?
Force the water through an electric turbine generator and that produces electricity. Having water backed up behind a dam provides the push.
Why is having a back up power generator important to have?
There are multiple benefits or having a backup power generator. Some of them are: you get a higher home value, cheaper insurance, you can have power when the main goes off.
What's the most efficient diesel generator I can buy?
Having a diesel generator for emergencies is a great idea. There is a great selection at www.dieselserviceandsupply.com .
If two sounds vary in frequency they are perceived as differing in?
pitch. A higher frequency sound will be perceived as having a higher pitch, whereas a lower frequency sound will be perceived as having a lower pitch.
Why do people choose or not choose this option?
If you live in an area where storms can interrupt you electrical power then having a generator handy will give you power in case of an emergency. Generally it is cheaper to buy the generator well ahead of storm season as the prices will rise as the demand for it rises. The operational cost during a storm will be the cost of gas which will vary depending on where you live.
