why fault current always calculated for 1 seconds?..

Answer / adnan

Fault current is too large, about 7 times the normal current. If this current flows for longer time, it will burn all the equipments. So, breakers are designed to operate in 0.3 sec, 0.5 sec time if fault is not cleared in this time.
So such large current, even 1 sec is too long time.
