Answer / c.b.t.

26.2kA am I right?

Answer / ranjan maithan

fault level depends on your system's percetage impedance.In
general practice we are using 28KA for 3 secs. or 40KA for
3 secs.

Answer / guest

c.b.t, can u plz exlain how u got tat answer,coz to b frank
i donno how to calculate the fault level of an electrical
system.

Answer / genau

Mr. Ranjan is correct!!
Fault level of the system will depend on the system impedance.

for calculation of fault level, calculate the fault impedance and hence you can calculate fault current from system voltage and fault impedance. product of two gives fault level in VA (Generally specified in MVA)
