Rotor Overheating Protection Diagram: Rotor Overheating Protection is provided only in case of large generators. It indicates the level of temperature and not the actual hot spot temperature. In the…

Rotor Earth Fault Protection of Generator: As we know already that field circuits are operated unearthed and it is not necessary to trip such a circuit completely if there is…

Negative Sequence Protection of Generator against Unbalanced Loads: If, owing to a fault, there is an imbalance in the three-phase stator currents, double frequency currents are induced in the rotor…

Generator Rotor Field Suppression and Neutral Circuit Breaker: In the event of a fault on a generator winding even though the generator circuit breaker is tripped, the fault continues to…

Loss of Excitation Protection in Generator: Loss of excitation protection in generator can endanger the generator or the connected system or both. It is caused by accidental tripping of field…
