Because Current always take low resistance path, i.e
Resistance is inversely propotional to Area,
means higher the fault current, lower the resistance,
Higher the conducting area i.e Earth terminal area is higher
than normal pins
R = ql/A, Resistance increases, area decreases

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?
