X-Ray Inspections for Circuit Breakers ​

How it Works

We Inspect the internal components of circuit breakers using advanced radiographic imaging. This process utilizes high-resolution X-ray images to detect internal defects, such as corrosion, misalignments, or mechanical failures, without dismantling the equipment. This substantially reduces outage times, SF6 emissions, and extends the life of your assets.

X-Rays vs. Traditional Internal Inspections

X-Ray imaging can be done in replacement of internal inspections. Here are some advantages:

  • Outage time reduced from days to hours
  • Return to service is less than 20 minutes
  • No SF6 gas handling or emissions
  • Know the condition of your equipment in the same day
