the impulse coefficient Kc of short circuit current in case of non-simultaneous short circuit in three phase A.C.circuit is a function of three variable.It is obtained by means of computer
Kc of lead phase circuit in two first short circuit phase has maximum.If the time constant of the circuit is 45ms
Kc=2.107
which is 1.17 times the valae in case of three simultaneous short circuit.
