The direction of conventional current is defined as the
direction of the flow of positive charges.Later,the charge
carriers were found to be electrons,posistrons ,or both in
opposite directions.In metal conductors the positive
charges are immobile and only 'negatively charged'electrons
flow.Because of electrons carry 'negative charge',the
electron motion in a conductor is the direction opposite to
that of conventional current.This convention ,though may
seem outdated ,is used worldwide.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
