Appendix C

SELECTED MAINTENANCE ACTIVITIES AND POSTMAINTENANCE TESTS

This list of activities and tests is a guide only and is not meant to be all-

NOTE:

inclusive. The testing selected should depend on the scope of completed

maintenance and the requirements established by the owner/operator.

An appropriate test for nearly all mechanical work would be a general

leakage inspection and any testing required by ASME codes or

equipment-specific procedures.

Maintenance Activity

Recommended Test

Repair Electric motor

Perform the following checks: insulation

index, high potential.

Verify proper direction of rotation and proper

phase relationships.

Operate the equipment and verify absence of

abnormal noises.

Obtain baseline vibration-analysis data.

Measure the bearing temperatures.

Measure the starting and the running current

for each phase.

Check oil levels.

Check air-filter cleanliness.

Repair circuit breaker.

Verify adjustment of circuit breaker trips.

Perform trip-shaft torque measurements if

applicable.

Measure phase-to-phase and phase-to-ground

insulation resistances.

Measure microhms across each main contact.

Perform automatic-function test on the

breaker (open and closes on required

signals).

Measure breaker-response time.

Verify operation of auxiliary trip devices and

Perform manual operation checks on the

breaker.

Check breaker parameters (e.g., breaker

operating voltage, current, control power,

status lights).
