After a long time to see you sir .. It's awesome again I am confused with pole slip protection before now I am very clear idea about it . Thank for this video .. Keep going sir .. We expect more videos like this from you sir.. Thank you.❤️🙏
Very nice explain and informative video's keep it up. Thank you. But one doubt/confusion , after carefully watching videos, At the starting of video's you shared information Relay sensing impedance through ct/pt units and released tripping command. But during whole video you will share information that relay travels zones R1,R2,R3 & R4 and count number of slip and released tripping command. So please clear my confusion with more explanation on how to calculate impedance internal/external etc. Information. Thank you
Relay sense voltage from PT and current from CT. When voltage is divided by current we get a complex quantity i.e. impedance written as R+jX. Every time there exists some value of R and some value of X, so when we plot R+jX in a 2D geometry RX plane we get some operating point. When this operating points changes slip occurs. Hope this explanation clarified your query.
Hi Thanks for the video. There is one question that in some relays settings are in i/Xd(Susptance) how to draw a Susptance diagram?? You had explained about how graph will work on R1 to R4 settings. But How to draw it in excel?? Any help? So i can get exact current and voltage value to run the test.
Sir ,i have a dout. In second situation where the fault is after GT. The relay should sense as external fault because the impedance will be greater then Zt and Zg.it will be in grid zone.
Very good explanation! Thanks for sharing
Excellent explanation.Lots of doubts are clear now.
Excellent explanation about pole slip protection and nice quality video..
It cleared all doubts about pole slip protection.
Thank u very much sir..
Welcome sir.. i thought you had left youtube.. but good to see again.. thanks

Thank you.❤️🙏
Dear atish sir.. its a long time not discussing with you.. btw ..its a great video.. i will try to catch zeist things.. thanx a lot
Very Good and Nice explanation
Nice explanation of complex concept.
Very nice explanation👍
Short and sweet explanation
Sir very use full , kindly put video for 100% stator Earth fault and rotor Earth fault protection
Thanks for sharing this critical protecttion
Thanks
Good explanation

@@electrocean6684 air,
Thank you very much for your great information and useful.
Thank you sir for making a nice video.
Welcome back here again
thanks, How do you propose troubleshooting?
Hi
Thanks for the video.

Sir
Thankyou for the information
Can u please correlate the setting n physical significance together
Sir ,i have a dout.
In second situation where the fault is after GT. The relay should sense as external fault because the impedance will be greater then Zt and Zg.it will be in grid zone.
Yes correct, take that fault in GT winding instead of terminal so that it will come below reactance line.
Man, you are champ
Thank You Very Much Sir
One doubt? Is R4 zone is motoring zone? Does it mean that machine will go to motoring zone in each slip?
Yes, both r3 & r4 are motoring zones
@@electrocean6684 OK. Thanks for reply
Sir, pole slip can occur in island mode of operation
🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Can you please explain Load angle limiter in the Excitation system.
Very good
just Awesome
Kindly upload video on backup impedance protection
For external dault which protection act backup impedance or negative phase sequence
*fault
Why load angle increases with increase in load... Please explain mathematically
Atish ho kya sir
