Abstract :
The authors report on and analyze a survey of practices and experiences with time-delay back-up protection associated with unit-connected generators, predominantly rated 100 MVA and above. In addition, application and setting considerations are discussed. The survey covered large unit-connected installations, involving 47 respondents and 6698 unit-years of experience. Phase back-up, negative-sequence overcurrent, and high-side neutral overcurrent protection were considered. The majority of respondents were found to apply all three classes of back-up protection: phase, negative-sequence, and high-side neutral overcurrent
