Ground-Fault Fast Transients in Modern unit-Connected Generators

摘要

In this paper the ground-fault overvoltages in the circuits of unit-connected generators during interrupted arc- ing ground faults in the stator winding of the generator with the neutral grounded through the ground-fault neutraliser were analysed. Comparative simulation tests of ground-fault volatages and currents for units with the biggest difference in parameters at the neutralisation coefficient equal to 0.6 were carried out.
