MOTOR OPERATION AND MAINTENANCE (ELECTRICAL
ENGINEERING) STUDY GUIDE WITH COMPLETE SOLUTION!!
A blank is used to periodically check the insulation resistance of the windings over
time to chart the progress of insulation and deterioration
answers: I Megger
If the ambient temperature is over blank due to an adequate airflow in the motor
location the motor service factor must be reduced or larger motor used
answers: 40°C
Motors are typically designed to operate it altitudes below blank
answers: 3300 feet
Voltage variation of not more than blank percent of nine plate voltage
answers: 10%
Frequency variation of not more than blank percent of name plate frequency
answers: 5%
Hey motor that receives a good maintenance will outlast a poorly treated motor
many times over
answers: Right right
The frequency and thoroughness of the maintenance and testing depends on such
factors as blank
