plz note the following statement
The design fault level depends on substation KVA rating the following table indicates the accepted KA rating levels for
the various KVA ratings of Substations
Transformer rating-1500KVA
MDB incoming ratings:60KA
MDB Outgoing ratings:55KA
SMDB Incoming Rating:35 KA
SMDB outgoing rating:25KA
folowing is the data i seen in one of design manual for the fault level calculation my question is what is the fault level and how to calculate and then its MDB incoming is taken 60KA and Outgoing 55KA similiarly SMDB incoming 35KA and its Outgoing 25KA how is it taken plz answer me I am entry level, electrical engineer
