o ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)
- 7. Verifying that. all automatic- diesel generator trips, except overspeed, generator differential. low lube oil pressure, crankcase overpressure, and failure to start are automatically bypassed for an emergency start signal.
- 8. Verifying the diesel generator operates for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
During the first 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> of this test, the diesel generator shall be loaded to greater than or equal to an indicated 2500-2600 kW and during the remaining 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of this test, the diesel generator shall be loaded to an indicated 2800-2900 kW. The generator voltage and frequency shall be 4160 i 420 volts and 60 t 1.2 Hz within 10 seconds after the start signal;.the steady-state generator voltage and frequency shall be maintained within these limits during this test. Within 5 minutes after completing this 24-hour test, perform Surveillance Requirement 4.8.1.1.2.a.4).* I
- 9. Verifying that the auto-connected loads to each diesel generator do not exceed the 2000-hour rating of 3100 kW.
- 10. Verifying the diesel generator's capability to:
a) Synchronize with the offsite power source while the generator is loaded with its emergency loads upon a simulated restoration of offsite power, b) Transfer its loads to the offsite power source, and c) Be restored to its standby status.
- 11. Verifying that the automatic load sequence timer is OPERABLE with the interval between each load block within i 10% of its design interval.
- 12. Verifying that the following diesel generator lockout features prevent diesel generator starting only when required:
a) 4160-volt ESF bus lockout.
b) Differential trip. <
c) Shutdown relay trip.
- If Surveillance Requirement 4.8.1.1.2.a.4) is not satisfactorily completed, l it is not necessary to repeat the preceding 24-hour test. Instead, the diesel generator may be operated at an indicated 2500-2600 kW for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> or l until operating temperature has stabilized.
