At 09:21 you said by tripping tbc cb fault will be isolated. Pls check incomer 1 will continue feeding fault. Pls write formula for zone a b & c

[@relayprotectionelectrical]

Since Incomer 1 is diverted to TBC..due to bus fault TBC 96 will operate as well as it will send DT to the HV or LV of the Transformer whichever is applicable and thereby it will isolate fault.
