Sir, how come there will be no variation in voltmeter and ammeter readings in stator side if the rotor is rotated at synchronous speed? If rotor is rotated at synchronous speed, its the rotor emf which is zero right? How it affects the stator readings?
Very nice explanation Sir.. Sir what is meant by the impressed voltage here and due to less armature current required as u explained how does it affects the voltmeter reading pls tell in more detail... I'm unable to understand at this point! Thanku
Sir please provide one video on synchronous machines field on stator and armature on rotor when running under steady state conditions air gap field with respect to relative speeds
Sir In 1.49 sec the stator magnetic field speed with respect to rotor is greater but the difference between stator feild and rotor speed is constant (Ns-Nr=constant) then how there Will be misallinment.
Very beautifully explained. Dear Sir, can you please share a video of determining +ve, - ve & 0 sequence impedance for cylindrical and salient pole alternator kindly. This will be very helpful. I too saw your power system videos but couldn't get anything. Thank you.
Hello sir, armature voltage and current indicated by the Meters are in the frequency of supply frequency(e.g. 50Hz) then how can I correctly identify the maximum and minimum values?
@@lecturesinelectricaleng Sir in above topic no doubt sir. In DC machine under polar axis emf max when flux linkage is minimum. please tell me above statement is either right or wrong
Sir can u explain me this sentence pls "During sliptest sometimes the induced emf in open field winding will be much more.The reason is the armature field rotation and rotor rotations are in opposite directions.Induced emf is much more and its Freq nearly double the supply Freq."

@@lecturesinelectricaleng Sir, Im talking about the case "If" rotor is rotated at synchronous speed, what will happen.

Sir one question Telephone Interference Test is also known as Slip test?
Perfectly explained
Sir please provide one video on synchronous machines field on stator and armature on rotor when running under steady state conditions air gap field with respect to relative speeds

Sir why we rotate the rotator below synchronous speed in this test? What if we rotate it on synchronous speed?
Very beautifully explained. Dear Sir, can you please share a video of determining +ve, - ve & 0 sequence impedance for cylindrical and salient pole alternator kindly. This will be very helpful. I too saw your power system videos but couldn't get anything. Thank you.

Thank you sir and if you don't mind, can I send some questions related to fault analysis via mail.
@@lecturesinelectricaleng
Okay sir. Thank you.
Excellent lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏
Please do one video on circle diagram
@@lecturesinelectricaleng thanks for your reply
Great explanation

Back emf opposition zero in open circuit, if it is closed path then opposition will exist or not sir?
Generally during polar axis emf maximum and in q axis emf min
Why it is failed here sir ?
In the above case i understood perfectly.
@@lecturesinelectricaleng
Sir in above topic no doubt sir.
In DC machine under polar axis emf max when flux linkage is minimum.
please tell me above statement is either right or wrong
Sir we find out the reactance from the EMF method that is equal to Direct axis reactance...what About Xq? I didn't understand at last 2 mints
Sir,how xs equals to xd in emf method?
Thank you sir ..... Awesome explained ever
Sir, why xd and xq are different for salient pole synchronous machine but same for cylindrical type alternator
DUE TO VARIABLE AIR GAP IN SALIENT POLE MACHINE
the video image is too poor, you need to fix it more
Why only 2 poles in stator Sir?
Sir why ia required more and less....if we have more reluctance ia will be less sir.. then how it will be more sir
flux remains constant as the v/f ratio is constant. as reluctance increase to maintain constant flux Ia increases.
Sir can u explain me this sentence pls
"During sliptest sometimes the induced emf in open field winding will be much more.The reason is the armature field rotation and rotor rotations are in opposite directions.Induced emf is much more and its Freq nearly double the supply Freq."
Thank you sir 😊
Namasthey sir... How voltmeter will indicate high voltage in aramature ckt when variac is low
Thank you sir. I will watch that video
