Inherent design protection of generators
WebbThe main purposes are to restrain the fault currents, the transient overvoltage and to improve the sensitivity of the earthfault protection. The grounding methods widely used are as follows: Ungrounded:This ungrounded method is common for the smaller generators especially when the machine's capacity is less than 10MW. WebbAll these factors make the design of protection scheme for the generator very much complex. Generator Faults. The various faults which can occur associated with a generator can be classified as, ... In case of power transformers, there is an inherent phase difference between the Voltages induced in high winding and low voltage winding.
