Pumps1 • direction of rotation • vibration • motor load versus time • seal or gland leakage • seal cooling • flow and pressure characteristics that demonstrate design-basis capability to deliver flow requirements at design pressure • lubrication • acceleration and coast down c. Dynamic Restraints (Snubbers)1 • visual examination • load rating • location • orientation • position setting • configuration • swing clearance • fluid level d. Motors and Generators • direction of rotation • vibration • thermal overload protection, margins between set points, and full load running amps • lubrication, cooling, heating, ventilation, fueling, starting , and exhaust, • Megger or hi-pot tests • supply voltage and frequency • phase to phase checks • neutral current • acceleration under load Appendix C to DG-1259, Page C-3 • temperature rise • phase currents • load acceptance capability versus both time and load (generators) • divisional redundancy and electrical independence • alarms, interlocks, and control functions e. Piping and Vessels • hydrostatic test • leak-tightness • cleaning, flushing, and layup2 • clearance of obstructions • support adjustments • proper gasketing • bolt torque • insulation • filling and venting f. Electrical and Instrumentation and Control • verification that sensing lines are clear for process sensors and that instrument root valves are open • voltage (i.e., operating ranges) • frequency • current • circuit breaker operation • power source identification • bus transfer schemes • trip settings • operation of interlocks, prohibits, and permissives • operation of standby power system logic and its loading sequence • calibration of relays (degraded grid voltage and loss of voltage) • control transformer settings • temperature
