Answer Posted / shailesh tankni
generators are basically synchronizing machine if a fault
occurs, they fall out of synchronization. but if the fault
is temporary or for a very small duration micro seconds or
seconds then the alternator/ generator may again achieve
synchronization without permanent interruption of supply.
this is the reason why the 95% protection is provided
instead of 100% protection.
otherwise for even for the small fault we would experience a
cut off eg: a small fault like contact of two phase
conductors due to sudden wind. which is a temporary fault.
