Why synchronous impedance method of determining voltage regulation is called as pessimistic method?
Because the saturation is not taken into consideration so the impedance calculated is more than the impedance that would have resulted once the saturation is taken into account.-- By Ankit(bigboss0086@gmail.com)
What is synchronous impedance?
Synchronous impedance is also known as the EMF method. It is a ratio of open circuits to short circuits, when they both are referred to the same field excitation.
Speed control method for synchronous motor?
True synchronous mode and self control mode
Which of the following is a method of synchronous online communication?
voicemail
Bioelectrical impedance is one method to determine body composition?
True.
What are the advantages of Transformer coupling method?
transformer coupling ensures maximum power transfer is obtained even if the output impedance is not equal to the load impedance
Is there any other method of damping the oscillation in a synchronous motor other than using damper winding and if yes what is it?
In synchronous motor hunting can be minimized using flywheel to the shaft .
What transmission synchronization methods uses the cyclic redundancy check method for error checking?
Synchronous
What has the author Homayoon Kazerooni written?
Homayoon Kazerooni has written: 'A robust design method for impedance control of constrained dynamic systems' -- subject(s): Manipulators (Mechanism), Mechanical impedance
What are the difference between LCR meter and electrochemical impedance spectroscopy?
LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
Can you suggest a circuit diagram for voltage regulation of 3 phase permanent magnet alternator for a constant output 230volts?
The normal method for controlling output of an alternator is to vary the field current. In a PM alternator, there would be no field windings to control. The only way I could think of would be to vary the speed of rotation. This might work if the output was rectified (DC), but would be a problem if the output is AC, since the frequency would also change. I have not seen a PM alternator per se. Unusual.
What is the difference between synchronous communication and asynchronous communication?
Synchronous just means "at the same time," so the difference is basically between immediate forms of communication. Here are some examples:Asynchronous communication:EmailMessage BoardsLettersBlogsVideo or Music recordingsOnline discussion boardsSynchronous communication:Phone callsAudio and Video conferencesIn person concertsInstant messaging / chatIn-person conversations / meetingsClearly the synchronous method is much faster, but the method that is best for a specific communication depends on the circumstances.
