Answer / dhiraj shringi
the power upto the fault in power system is known as fault
level power.
it is calculated by the following formula:

Answer / mahesh sali
As per IEC std. Low voltage fault have decide as below
mentioned ranges.
For 50 KA / 65 KA at 1 or 3 sec.
for cal Fault current KA - ( KVAsc/ %sub transient
reactance ) *100
thanks
