I have one ct of ratio 3000-2000/1 Amp its knee point voltage mentioned on name plate is 500-333/30mA-50mA at Vk/2. in secondary box there is three terminal named 1S1, 1S2, 1S3 then on which terminal obtained the knee point voltage ie 1S1-1S2 OR 1S1-1S3 & also specify the knee point voltage for the ratio 3000 from name plate.
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.
