define ac reactor? thier application;
Answer / k.prakashchandra
In order to limit short-circuit currents to a value which
the CBs can handle ,additional reactances called as reactors
are connected in series with the system at required
points.Earthed 3phase variable reactors are used in stations
to overcome the Ferranti effect.

I am having a 1500 KVA transformer whose secondary current is 2086A and my connected load is 1000 KVA, I am having 400 KVAR APFCR for PF improvement what ratio of CT should i install in LT EB Bus to get optimum PF improvement?
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?
