Method and apparatus for determining generator ventilation system failure using two differential pressure sensors |
摘要 |
The ratio of the pressure change across a portion of the ventilation system of a hydrogen cooled electric power generator to the pressure increase across a reference blower, preferably the purity blower, is compared to a base ratio to generate an alarm when the difference in ratios exceeds a predetermined amount indicative of a failure within the ventilation system.
