| Arizona Public Service Company, (APS), Arizona’s longest-serving electric utility, uses SmartSignal at the Palo Verde Nuclear Generating Station to monitor a wide range of equipment, including feedwater pumps, reactor coolant pumps, steam generators, and related plant equipment. |
| |
| At Palo Verde, SmartSignal has detected statistically
significant deviations in pump seal staging pressure in
the 5 PSI range that indicate the onset of seal degradation,
whereas traditional techniques require at least 10-15 PSI
deviations. The high sensitivity of the SmartSignal product
provides as much as
two months early warning compared to traditional methods.
Early warning improves scheduling, reduces maintenance
expenditures, and delivers exceptional value to nuclear
power plants. |
