Why shaft generator can not operate in parallel with auxiliary generator?
Normal shaft generators do not have droop-control for frequency and voltage. Semiconductor (drive) based variable speed shaft generators may have those today.
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 many generator we can operate in parallel in a system?
In a grid system all the alternators run in parallel, locked together in frequency.
Why is necessary to control over speed in a motor?
over speed control is recommended for all prime mover driven generator to prevent over frequency operation of load connected to a system supplied by the generator and also to prevent possible over frequency operation of the generator itself from Ac system.
Which IC is used as clock generator in 8086?
The 8086 Microprocessor operate to require frequency that is provided by clock generator to 8086 Microprocessor and also Synchronization various component of 8086.
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.
What is baud rate generator?
baud rate generator is a frequency divider
When you rotate the handle of the electric generator faster does it deliver more less or the same voltage?
The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.
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.
What frequency do household remote control electronics operate on?
The frequency of remote controls for the television varies from brand to brand. The ones that do operate using radio frequencies though are all generally low frequencies. Most remote controls today operate using infrared light signals though.
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.
