URD Padmount Inspection

Aged, corroded and severely weathered padmount transformers can contribute to outages, safety hazards and customer complaints. The majority of America’s underground distribution systems are more than 30 years old.

Osmose padmount transformer inspection and maintenance programs are supported by the company’s commitment to safety, training, project management, and effective applications of technology.  Osmose crews are trained and certified to:

  • Safely inspect padmount transformers
  • Identify potentially troublesome conditions
  • Record accurate inventory information
  • Remove debris, insects, and pests to help reduce the possibility of electrical failure
  • Apply pesticides inside the cabinet to help prevent future pest activity

Laser-guided infrared can be used to detect elevated temperatures on critical transformer components, such as primary elbow connections.

Padmount transformers that are not level can overheat and fail. Osmose crews can correct this condition by leveling the pad and back-filling with materials specifically formulated for this task.

Osmose inspection and maintenance techniques can help improve the safety, reliability, and appearance of padmount transformers and cabinets, adding years to their useful service life.
