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.

Too long. Keep it max 20 minutes. Otherwise good, informative
