notesInspection Checklist:Upon delivery and prior to unloading:Upon delivery and prior to unloading:1. Inspect equipment for any damage that may have occurred during shipment or storage.

2. Verify that the tie rods and chains are undamaged and tight and that all blocking and bracing is tight. Check that there is no evidence of load shifting in transit.

3.Check reading from impact recorder and compare with manufacturers recommendation.

4. Check for indication of external damages, dents or scratches in doors, tank walls, radiators and fins, termination compartments.

5. Check for evidence of insulating liquid leaks on transformer surfaces, at weld seams, on high and low voltage bushing parts and at the transformer base.

6. Verify that there is positive pressure or vacuum on the tank. Check pressure gauge. Gauge readings other than zero indicate that the tank is properly sealed. (Alternatively, pull the pressure relief valve ring, if equipped and released instantly or loosen the vent plug. The sound of rushing air indicates that the unit has maintained an effective seal. The absence of rushing air sounds may be evidence of a leak.

7. Compare transformer and accessories received with the bill of material to verify that the shipment is complete. Verify that transformer and accessories conform with the 3 manufacturers quotation and shop drawings. If the shipment is not complete or does not comply with project requirements, notify the manufacturer in writing immediately.

8. Unload transformers carefully, observing all packing label warnings and handling in accordance with manufacturers recommendation.

9. Open termination compartment doors and inspect components for damaged or displace parts, loose or broken connections, cracked or shipped insulators, bent mounting flanges, dirt or foreign material and water or moisture.

10 When condition indicates the likelihood of a damage, file a damage claim with the transport company and notify the manufacturer in writing immediately. Consult the manufacturer for recommendation before returning transformers to the manufacturer for inspection and repairs, rejecting transformers, repairing or replacing components, or performing additional labor.11. Check/verify PCB contents.

HANDLING:

1. Handle transformers carefully, in accordance with manufacturer recommendation, to damage to the enclosure, termination compartments, base, frame, tank and internal components. Avoid subjecting transformers to impact, jolting, jarring, rough handling, etc.2. Protect transformer termination compartments against the entrance of dust and rain when handling outdoors during inclement weather.

3. Verify that transformers are transported in the upright position to avoid initial stresses on the core and coil mounting assembly and to prevent trapping air in the windings. Do not tilt or tip transformers.

4. Verify that transformer weights are within the rated capacity of the handling equipment to be used.

5. Ensure that personnel are kepy at a safe distance from transformers while lifting and handling.

6. Use the manufacturer recommended points for lifting, jacking and/or pulling transformers. Do not lift or drag by placing a loop or sling around the transformer. Do not use radiator fins for lifting or jacking. Use all lifting lugs when lifting transformers. (Lifting lugs or ears are designed for vertical strain only.)

7. Use jacks at the corners of the tank base plate. Do not place jacks under radiator pins, termination compartments, drain valves, pipe connections or other attachments.

8. Use nylon straps of the same length to balance and distribute weight when handling transformer with a crane.

9. Use spreader or lifting beam to obtain a vertical lift and to protect the transformer from straps bearing against the enclosure. (Lifting cable pull angles should not be greater than 15 degrees from vertical.

10. Exercise care not to damage the tank base structure when handling transformer using skids of rollers. Use skids to distribute stresses over the tank base when using rollers under large transformers.
