SCENARIOS OF OPERATING AND MAINTAINING A FACILITY ARE COMPLEX AND HUMANLOGIC IS A REQUIREMENT. PROCEDURES ARE INTENDED TO ASSIST EMPLOYEES INPERFORMING THEIR DUTIES. ALTHOUGH MAINTENANCE PROCEDURES ARE A BEST
ATTEMPT AT DETERMINING EVENTS, THEY ARE NOT INTENDED TO REPLACE THOUGHTAND LOGIC. MAINTENANCE EMPLOYEES ARE EXPECTED TO SAFELY AND EFFICIENTLYMAINTAIN AREAS FOR WHICH THEY ARE QUALIFIED, EVEN IF A PROCEDURE DOES NOTEXIST. IT IS THE MAINTENANCE EMPLOYEES RESPONSIBILITY TO INFORM SUPERVISIONOF PROCEDURES NEEDED WHEN IDENTIFIED.
IF THERE IS A MODIFICATION REQUIRED TO THIS PROCEDURE NOTIFY THE AREASUPERINTENDENT IMMEDIATELY. AN MOC IS REQUIRED FOR ANY PROCEDURAL CHANGE
FOLLOW AREA SUPERVISION FOR ANY DEVIATION FROM THIS PROCEDURE.
Purpose: To have a ready scope of work and checklist for Preventative Maintenancwork on 2400 V motors and starters throughout the refinery. To be usedwhen the opportunity to do such work presents itself.

Several motors in the refinery have multiple sources of power; Secureall power sources before proceeding with the PM.
Some control circuits have multiple power sources; ensure all voltageare dead before proceeding.
Some contacts mounted on the starter could also have power on
them from different sources All Equipment tested must have warning Signs posted.
Check all Testing Equipment for proper calibration.

Preventative Maintenance for 2400V Motors
Scope of Work
Verify with Operations that the motor can be worked on.
Caution: Ensure all power has been removed, the starter has been locked out and tagged o
and the starter aux. contacts are de-energized before proceeding.
Starter visual inspection: Make a thorough visual inspection of the starter and all its components.everything looks alright, mark yes on the form. If you notice something is wrong, and you can fix iteasily, do so. Make note of your repairs in the comments section. If there is a major problem thatcant be fixed easily mark no on the form and write the problem down in the comments section forlater repair. Record the overload number in the appropriate spot on the inspection form.
Oil filled starters and start/ stop stations: Check the oil level, to ensue there are no leaks. Drain
and refill the reservoirs. Follow the procedure for disposal of waste oil (PH-442-MP-1001).
Air Fi lter: Inspect the air filter for cleanliness, if there is one. Clean or replace as needed.Main Contacts Inspection: Open the compartment that houses the main contacts. Inspect thecontacts for pitting, burning, & charring. Rate the contacts, Good:being very little damage to thecontact, Fair: being some damage is present but the contact is still serviceable, Poor: The contactsneed replacement as soon as possible.
Before Using Test Equipment on Energized parts, you must fi ll ou t Test Equipment CalibratiSheet.
Check Connections: Caution: the line side of the breaker is hot! All other connection pointsshould be checked to verify they are dead!! Using a torque wrench as required in tighteningconnections. Mark Yes on the inspection form if all connections are tight, and mark No if you hadto re-torque any connections. In the comments section mark how many connections you had to re-torque.
Testing Electrical Equipment: A danger high voltage testing placard sign must beon the ElectricEquipment under testing.Sample of sign posting

Baker Surge Tester: We now use the new computerized baker surge tester, which performs all thnecessary testing for both the 2400V and 480V motors. All you need to do is enter the properinformation, and follow instructions. If baker surge tester is not available use a 5000V, Megger on t2400V motors. If there is a surge arrestor connected to the motor it must be disconnected beforetesting, to prevent false readings to ground.
Megger Motor:Perform a 1 minute (or long enough for the reading to stabilize) Megger reading ofthe motor windings to ground, which should be done from the starter, the baker dose this
automatically, or you can use a 5000V Megger. Record the reading in the appropriate space on thePM sheet. Readings below five Megs are unacceptable. A reading should also be taken to ensurthe windings are closed in the A/B, B/C, C/A phasing format. You should also use the MICRO-OHMmeter to compare phase to phase resistances if you are not using the computerized baker surgetester, which must be done from the motor connection box.
Megger Control Wiring: Caution: some control devices are sensitive to voltages higher than120V ensure none of these devices are in the control circuit before proceeding!In most casethe groundside of the control transformer must be lifted for accurate readings. Perform a 1 minute long enough for the reading to stabilize) Megger reading of the control circuit to ground. This shouldbe done with a 500V Megger, from the starter. Record the reading in the appropriate space on the
PM sheet. Readings below one Meg are unacceptable.
Nameplate Data: Record the nameplate data on the check sheet where indicated.
Motor Connection Box Visual Inspection:Open the Motor Connection Box Inspect the box andconnections for signs of water / oil damage. Repair as necessary. Inspect the connections fortightness, insulation damage, & wear from vibration, on the taped or booted connection.
Control Station Visual Inspection: Open the control station and inspect for damage, repair orreplace as necessary. Indicate findings in the section provided on the PM sheet.

TheBelleville washer is now flat. It is not necessary to back off the nut after tightening to this point.Remove all corrosion and surface oxides along contact areas.Coat contact surfaces with an appropriate oxide inhibiting compound. Such as; Penetrox A or similafor AL-AL or AL-CU (verify voltage limits if any) Not recommended for rubber or polyethyleneinsulated conductors.
Use Penetrox E or similar for CU-CU connections all voltages.Plated surfaces should not be wired brushed. Use an appropriate cleaning solvent or similarcompound that does not disturb the integrity of the plating.
