Adaptive 100 % Stator Earth Fault Protection Based on Third Harmonic Voltage Measurement


Short circuit between the stator winding in the slots and stator core is the most common type of electrical fault in generators. According to a big US utility, 70 to 80 % of all electrical faults in their generators have been – or started as- earth-faults of the stator winding. The protection described in the paper is capable of detecting earth faults occurring at any point of the stator winding, and i
