Generator Faults: Generator faults can be considered under the following heads. (a) Stator Faults: These include the following: Phase-to-earth faults. Phase-to-phase faults. Inter-turn faults. Most faults occur in the stator…
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…
Generator Inter Turn Fault Protection: Merz-Price circulating current protection system does not provide protection against turn-to-turn faults (short circuits between the turns) on the same phase winding of the stator…
Self Balance Protection System of Generator: It necessarily consists of two cables connected to the two ends of each phase and the cables are passed through the circular aperture of…
Percentage Differential Relay Protection of Generator: This system, also called the Merz-Price protection system, is the most common type of protection used for stator windings against phase-to-phase or phase-to-ground faults.…
Different Types of Faults in Power System: A fault in an electrical equipment/apparatus is defined as a defect in the electrical circuit due to which current is diverted from the…
