Is LV shorted in magnettic balance test?If yes why?
Answer Posted / tanmay kumar
generally magnetic balance test was done in transformers to know the ratio that means to check its rating whether it is giving the output or not as per the rating,,,in case of magnetic balance test the voltage feeded at the primary side always i.e l.v side and the secondary side is at no load i.e open ckted and a tongue tester is used to measure the amount of flowing current from primary to secondary.

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.
