fault current flowing through secondary of CT is less than
preset value for relay operation.Hence relay will not
operate for that much portion of winding.

What effect does a very low impedance have on the Voltage regulation? On the short-circuit current?
If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
