Thank you sir 🙏
Thank you sir
Thankyou very much sir .Your assistance helped me lot to understand the design requirements
@@hemachandarg share it widely
sir, I am so happy that you are back.Your courses were immensely helped me in my career.I just want you know that my friends who are working in ABB,Schneider and General Electrical are also your subscribers.We greatly appreciate your efforts.Please continue the series
@@jeevankoshy9027 sure
Sir why then we use low impedance differential protection
Where there is a chance of CT ratio mismatch and / or polarity change and / or CT used mixing with new and old and / or CT s are different make type etc, it is better to use low impedance differential protection. Moreover, low impedance protection work on current value but high impedance work on voltage across the relay terminal. Low impedance system: each CT wire needs to be connected to the relay but high impedance it is not so. Future feeder expansion may be difficult while the protection is low impedance type
Thank you sir for coming back making video..really appreciate this.
@@kucingpowergile share it more with your friends , colleague
This lecture is uniquely amazing and essential for Protection & Control Engineers. Just a couple of minor points: I believe device no. 80 is a Liquid or Gas Flow Relay, not a DC current flow relay. Also, I couldn't find a reference for 99 being used for transformer over-fluxing protection; it seems to be device number 24. Thanks for the great lecture!
80 is flow switch which could be liquid, gas , power etc. As we are dealing electricity , we can use it for Power switch change over scheme as an option 99 is not assigned yet but we can use it as per our convenience. Some engineer use it for overfluxing / over excitation .
@@amppowersystem6084 Isn't device number 24 already designated for over-excitation? Could you please provide references for using device numbers 80 and 186 for electrical current flow and auto-reclose lockout functions? Thank you, Sir.
SIR PLEASE MAKE A VEDIO FOR THREE PHASE 415 VOLTS CABLE SELECTION FOR MOTORS IN INDUSTRIES
Very useful Sir. Thanks.
Top class lecture thanks sir
Very good information sir
Excellent
Thank you verry much
You have not discussed 78 and 64R protection
Sir kindly give ur number so that i can clear my doubts. Your teaching skills are exceptional

extremely good class.. thanks for your valuable time.
Very good lecture. thanks
Hi sir classes are good.do u give training on switch gear panel designing
Excellent 👍
Amazing session. Pls uploading sir more videos like this
Keep uploading sir🙏
Mind blowing sir😊
Excellent presentation
Excellent 👌
Plz make video in Hindi language thank you
Uncle g Hindi m btate to hm bhi samjh jate
Sir can get your contact no
Thank you for sharing your knowledge.
Excellent lectures for new learners.Thank you sir for sharing knowledge.
Sir, IEC does not mention in case we use XLPE current rating against 90deg max temp of its insulation This rating will bring conductor to equilibrium temp 90 degree which is not suitable for terminal of equipment which rated only 75 degree. In this case, How to rectify this problem?
It shall be read as conductor temperature on continuous rating and not insulation. Slip of tounge
How you categorize load as continuous or intermittent Load? When you have Pump with as following : 1. Running in 1 hour per day 2. Running in 3 hours per day, then standby 3. Running ini 6 hours per day, then standby 4. Runninh in 12 hours per day, then standby 5. Running for 75 hours per day, then standby. What you classify above motor respectively ? As continuous or intermittent Load? I have Terminal LPG Plant that the pumps running as above condition, and it decided to sizing of 3.3 kV Bus Bar and Power Transformer.
Good explanation sir
All the 3 CT shall be connected to relay always. But in your video CT connected in phase side, shows one phase CT only with one relay and explained fault happen on other phase will not detect by other CTs. Why dont we connect the CT in same way as in neutral side, so relay will find the fault?
I dint get you friend. 3 CTs shown on the neutral side for 51v protection. Time ref 4.37 minuts onward Can i request your support to look in it and send me the screen short where you have noticed it. Many thanks for looking into this presentation. Regards Paul
Further to this , here generator is the source and if the fault ahead of CT towards generator fault current will not appear in the CT secondary and relay will remain in active .
Sessions of Sir are like rarely found precious gems
Thank you
This video helped me a lot in understanding the ratings of a generator. Thank you so much.
Thank you sir very useful informations
Very informative
very hard to understand
If you kindly let me know the exact point i may help you
Very informative and nice explanation, thank you sir for sharing these valuable informations. Appreciate your efforts.
Very informative lecture sir
Gem... Exceptional
this is one of most under rated lecture dr you are the only one who made me understand the different characterises in this beautiful manner thank you for your time
How much KW motor should be considered as largest motor(separately). If the motor KW is less than 400KW and base load is 1500KW, then can be considered as combined load.
