Answer Posted / gulshan goyal
MAINLY THERE ARE TWO TYPES OF FAULTS SHORT CIRCUIT AND OPEN
CIRCUIT FAULTS.IN SHORT CIRCUIT FAULTS WE STUDY ABOUT
SYMMETRICAL AND UNSYMMETRICAL FAULTS.THE THREE PHASE FAULT
WHICH IS RARE MOST SEVERE FAULT IS SYMMETRICAL FAULT.AND
LL.LG ,LLG ARE UNSYMMETRICAL FAULTS.By performing short
circuit MVA analysis for positive, negative and zero
sequences, symmetrical three phase
and unsymmetrical phase-to-ground, phase-to-phase and
double phase-to-ground fault currents can be resolved.
