Differential protection is primarily used to clear any internal faults in the stator winding of a generator or alternator. Current Transformers: Two sets of current transformers (CTs) are used, one on the line side and one on the neutral side, and their. . designing generator protection and control: Reliability, which is dependability vs. Effectiveness, balancing speed vs. selectivity Some resources for settings include Relevant guides and standards (IEEE, IAS) Requirements of regulatory and the interconnecting utility (NERC. . Abstract—Differential protection is often touted as being The protection for generator stator windings. In this paper, we examine the degree of protection afforded by the various types of differential elements (phase, negative, and zero sequence) for stator winding faults.
