when two phases shorts it means short circuit. so high
current wil flow through fuse. so its get blown.

Answer / shakir

when we short two phases the resistance between them is 0 and
current goes to infinity (I=V/R). such an infinite current
when pass through a fuse,the fuse gets blown.

Answer / vasudeva rao

two pase gets shorted means (L-L fault) in this fault phase
currents are very high

because it double the voltage which leeds high resistence
then the fuse should blowen of.

In alternator generally we give DC voltage to field of alternator but field (excitor)produce Ac & converts into DC by rotating rectifier(RR ) then fed to rotor .my question is why we cannot give dc voltage directly to rotor instead of Excitor & RR ?
