Auto means automatically open/close of breakers with momentary paralleling Manual means manually open/close of breakers with momentary paralleling. What does independent means? Does in independent mode bus coupler remain open? Please explain independent mode and when its used?
Cinimatography doesn’t matter as long as you filling contents which are informative. Thanks for this video. And those And, Not, Or logic gated, where will it be implemented? Inside multifunction relays with programming or via hardwiring of manual NO/NC relays ?
Good question. We can give it directly. Because yes it has no such significance like under voltage. But there is another reason, that adding multiple relay on 86 will increase its burden. So the most common one 51, 51N is fed to 86. And if Ref has operated 51 n is also likely to operate
Refer to service logic block, 1st stage Upper side "AND" gate in diagram; I/P (2) bus-coupler open I/P (3) I/C-2 open So this case the closing command of entire control logic logic should be to close either bus-coupler or I/C-2. Refer to service logic block, 1st stage Lower side "AND" gate in diagram; I/P (4) bus-coupler close in service I/P (5) I/C-2 close in service So this case the closing command of entire control logic should be to close I/C-1. So which "incoming breaker closing" command is defined by this entire Control logic. ?
Very nice way of explanation, upload more videos
wonderful explanation thanks a ton
Thank you sir
Nice videos sir.
Please give some highlights on synchro check relay connection with SYNC. Check selector switch.
Regards
Super
Auto means automatically open/close of breakers with momentary paralleling
Manual means manually open/close of breakers with momentary paralleling.
What does independent means? Does in independent mode bus coupler remain open? Please explain independent mode and when its used?
Momentary paralleling happens only in manual. Auto means auto changeover. And independent means simple interlock
@@electricaltechnologyandind5335 Does bus coupler remains open in independent mode? Bus PT-1/2 remains dead in independent mode?
Thank you so much sir! Which book you are referring sir? Please let me know!
these are not taken from book. but from practical experience and drawings.
Thank you sir

It can be done through numeric relays, it can be done though no nc contact. In the next video i will explain the circuit
Sir why REF is given direct instead of
Giving to 86 master relay. Any significance in giving directly like undervoltage

First one independent mode is interlock scheme. Second one manual mode is momentary paralleling scheme.
ELECTRICAL TECHNOLOGY and INDUSTRIAL PRACTICE Agreed. But which breaker will be operated? Can u please explain case scenarios?
Plz hindi me explain kr diya kro
