1. Purpose

This procedure provides a safe, standardized approach for the initial inspection, checkout, testing, and data documentation of electric motors used to drive rotating equipment.

2. Scope

This procedure is applicable to the SALAVAT Project Site and covers all motors. It applies to ac and dc motors used to drive rotating mechanical equipment. Motors used as operators for valves, gates, dampers, etc. are not within the scope of this procedure.

This procedure shall be implemented during initial uncoupled/unloaded operation of applicable equipment, as well as during the initial coupled/loaded operation. However, it may be used at any time during equipment operation.

3. Definitions

• Project : Gazprom Neftehim Salavat Acrylic / Acid Plant • Company : Gazprom Neftehim Salavat • Construction : Renaissance Construction (RC) • Supplier (Manufacturer/Vendor) : The supplier (Manufacturer/Vendor) is the party that

manufacturers or supplies equipment and services to perform the duties specified by the Company or Contractor.

• The word SHALL indicate a requirement. • The word SHOULD indicate recommendation.

• Drive End (DE) - The end of the motor from which the shaft protrudes and is coupled to the driven

equipment. It may also be referred to as the inboard (IB) end of the motor.

• Non Drive End (NDE) - The end of the motor that is opposite the DE. This end of the motor usually has the motor’s cooling fan attached. It may also be referred to as the opposite drive end (ODE) or outboard (OB) end of the motor.

• Bump - To start and immediately stop a motor from a control switch to verify direction of rotation.

• Rotation - The rotation of a motor as viewed from behind the NDE, standing with line of sight in-line with the rotor, looking toward the drive shaft of the driven equipment.

• Magnetic Center - That position of the motor rotor where the magnetic forces acting on the rotor are in balance during operation. In large motors during initial run-in, the magnetic center is marked to allow positioning of the rotor at the magnetic center for coupling alignment. Placement of the rotor at the magnetic center assures that no thrust from the motor is transmitted to the driven equipment via the coupling.

• Motor Doweling - A practice on some large motors where the motor base is drilled and dowels inserted to prevent movement of the motor. This is usually done to permanently fix the final alignment position of the motor. In some cases the driven equipment may also be doweled in place.

6. Procedure

NOTE: The vendor’s instruction manual takes precedence over this procedure in the event of conflicts. Detailed equipment operation shall be according to vendor manuals.

6.1 General

6.1.1 This test shall be performed concurrently with the Equipment Vibration Testing Procedure. The Test Engineer will coordinate all activities as necessary.

6.1.2 Motor run-in time shall be as specified by OGK4 CSU until bearing temperatures and winding temperatures (as applicable) stabilize. A temperature is normally considered stable when three successive readings taken at 10-minute intervals do not vary by more than ±5 percent. A 4 hours run-in time shall be considered adequate for all motors with 400 V ac or 125 V dc supplies.

6.1.3 During initial run-in, record those equipment parameters that have an accessible indicator. Typical parameters that establish the motor's characteristics include bearing temperatures, winding temperatures, cooling fluid temperatures, lubrication flows and temperatures, etc. The data should have a common time basis and be recorded at a specified interval. The following are several acceptable recording methods: • The plant DCS or computer

• A chart recorder

• A data logger

• Manual recording of local indicators

6.1.4 Use the Motor Data Record, Exhibit 1, to document test results and attach charts, graphs, data printouts, etc. Data collection can be stopped when monitored parameters have stabilized.

6.1.5 During the coupled run-in of variable or multi-speed equipment data should be taken at: • Minimum (or low) speed.

• Anticipated normal (or medium) speed.

• Maximum (or high) speed.

NOTE: On variable speed equipment, particular attention should be exercised to avoid operation at, or near, the equipment critical speed.

6.1.6 Temporary alterations installed during testing shall be recorded on Exhibit 1, Motor Data Record. Temporary alterations that are to remain following completion of testing shall be logged according to the requirements of the Control of Temporary Modifications Procedure.

6.2 Inspection

6.2.1 Ensure that the motor is clean and dry. The motor nameplate shall be legible. End bells, covers, filters, and accessories shall be firmly attached.

6.2.2 Record motor nameplate data on the Motor Data Record, Exhibit 1.

6.2.3 Verify that the voltage, phasing and the frequency of the motor’s power supply agree with those on the motor nameplate and the appropriate drawings.

6.2.4 Verify that motor terminations are properly made up. On dual voltage motors ensure that the connections are correct for the supplied voltage.

6.2.5 Verify that the motor is properly grounded in accordance with the project grounding notes, symbols, and details.

6.2.6 Inspect collector rings and brushes. The collector rings shall be clean and free of any mechanical damage. The brushes shall make good contact with the slip rings and the brushes shall slide smoothly in their holders.

6.2.7 Verify that the motor protection circuits have been set. If Engineering has not provided initial settings the following may be used:

• Instantaneous trip (magnetic overloads or quick blow fuses) is the locked rotor (LR) amperage if given on the name plate

• Timed trip (thermal overloads or slow-blow fuses) is set at 1.05 FLA

Record the initial settings in the comment section of the Motor Data Record, Exhibit 1.6.2.8 Verify that all protective relays have been calibrated and functionally tested.

6.2.9 Inspect conduit connections for control and power cables ensuring that bushings are installed, conduit connections are tight and covers are installed.

6.3 Pre-Run Tests

6.3.1 The insulation of the motor windings and power cable should be meggered prior to the initial run if not recently meggered.

6.3.2 The winding resistance and the applied voltage shall be measured phase to phase.

6.3.3 Support systems, such as lube oil or cooling water, shall be placed into operation.

6.3.4 The motor shaft shall be manually rotated (if possible) to ensure that the rotor moves freely, without rubbing.

6.3.5 Phase rotation may be initially checked using a motor phase rotation meter for any motor. However, an initial check by actual motor rotation (bump) is mandatory for motors and driven equipment that might be damaged by reverse rotation:

a. Lock out / Tag out the motor supply breaker.

b. Connect the leads of the phase rotation meter to the motor terminals at the motor terminal box or feeder (load) terminals for the motor at the starter or switchgear.

c. Slowly rotate the motor shaft (rotor) in the proper direction of rotation for the driven equipment and verify that the phase sequence on the meter matches the phase sequence of the line (supply) connections.

d. If the phase sequence indicated on the meter does not match the design (line) phase sequence, interchange the motor leads of two phases at the motor terminal box or at the starter or switchgear.

NOTE: If leads need to be swapped all labels, tags, markings, etc. need to be revised to match issued drawings.

e. Recheck the phase sequence of the motor winding using steps b. and c. above and record the sequence on the Motor Data Record, Exhibit 1.

f. Remove the Lock out / Tag out.

6.3.6 For a motor supplied from a load center or switchgear bus, place the breaker in the operating position (racked-in). For a motor equipped with a starter and supplied from a motor control center and/or distribution panel, place the breaker in the closed position. Verify that the motor space heaters, if supplied, are energized and note their operation in the comment section of the Motor Data Record, Exhibit 1.

NOTE: Space heaters must energized for the minimum amount of time required by the manufacturer prior to attempting a motor start. If no guidelines are given the heater should be energized for 8 hours prior to attempting the start.

6.3.7 After the preliminary rotation verification all motors must be “bumped” for a final verification of proper rotation.

6.3.8 Ensure that the safety switch adjacent to the motor is function checked before starting motor.

6.4 Motor Start and Run

6.4.1 If, at any time during the implementation of this procedure, any parameter or condition is out of acceptable limits and cannot be readily corrected, the evolution in progress shall be terminated and the system or component placed in a safe configuration.

6.4.2 Clamp an ammeter on one of the motor leads at the breaker and set it to record the maximum current draw. Alternatively if the motor manager or protection relay can record starting current, this should be used instead of clamp on ammeter. Start the motor, locally if possible. Record the starting current on the Motor Data Record, Exhibit 1.

6.4.3 As the motor comes up to speed, monitor it for smoothness of operation and for any unusual or unexpected noises.

6.4.4 with the motor running: take running current on all phases, phase to phase voltages, and motor rpm measurements and verify that the motor space heater is de-energized. Record readings on the Motor Data Record, Exhibit 1.

6.4.5 If applicable tune variable speed drive to the system attributes and verify frequency settings.

6.4.6 Check that the motor bearings are being properly lubricated (e.g. bearing oil rings are rotating, no excessive foaming, levels are correct). Monitor bearing temperatures as the motor is run in. When they have stabilized, record the measurement.

6.4.7 Monitor motor winding temperatures, if available. When they have stabilized, record measurements on the Motor Data Record, Exhibit 1, in the comment section.

6.4.8 Take vibration data as required. Refer to Equipment Vibration Testing Procedure. Vibration readings that exceed limits may result in motor damage, and operation may have to be secured.

6.4.9 Verify temperature, current, and vibration readings against any local or remote indications.

6.4.10 Verify magnetic centre position indication, if applicable. Apply new mark if necessary.

6.4.11 When the vendor’s run-in criteria have been met or the temperatures are stable secure the motor and monitor for smooth coast down.

6.4.12 Repeat the activities of the uncoupled motor start and run-in when the motor is coupled. Record the data on the Motor Data Record, Exhibit 1.

6.4.13 After final alignment and motor and driven equipment run-in, the motor may be doweled in position as required by the vendor.

6.4.14 Ensure that motor stops when safety switch is put in off position and cannot be started again from PCS.

6.5 Restoration 6.5.1 Verify that temporary alterations made during the performance of this test have been

restored or controlled according to Control of Temporary Modifications Procedure.

6.5.2 Verify that temporary test equipment has been removed, and all system connections and permanent equipment are replaced and secured. Ensure terminal box cover is tight and has appropriate gasket installed.

6.5.3 Verify that equipment and system(s) affected by this procedure are restored to conditions as specified by the person responsible for the system(s).

6.5.4 Verify that applicable Thule Data Records have been completed.
