The product of normal system voltage and short circuit
current at the point of fault is fault level and is equal to
3 Vph(normal) x Isc for symmetrical fault in 3 phase
system.It is expressed in KVA or MVA

Answer / amit khamesra

Short circuit levelof the system defines its mechanical
strength to bear the enormour fources and heat developed by
short circuit current. To revamp a systm from 40 KA to 50
KA capacity, more no. of insulator suppors are required
along with increase in busbar current carrying capacity.

Answer / isaac p

Fault level is a point where the normal operation level
has been exceeded and the system shuts down or other
components are called to rescue the situation.

Answer / tarak mehta

It is the value which is exceed the normal value from where
the system can not ragain its healthy condition.
