Electrical Equipment Leak Repair

Team’s technicians economically perform nondestructive onsite, in-place leak repairs for a wide range of electrical equipment.

• Transformers (without draining oil)
  
• Circuit breakers leaking SF6 gas and/or oil
  
• All flange and flange ends
  
• All valve packing
  
• Expansion joints
  
• Bolted cover plate (tap changer)
  
• Porcelain bushings (flange and joint)
  
• Weld leaks
  
• Induction motor flanges
  
• Circulation oil pumps
  
• Standard line flanges
  
• Bolt threads
  
• Radiator cooling fins, drain plug caps

Transformer Leak Repair Advantages

• Below-the-top repairs often can be made with transformers in-service
  
• The need to drain transformer oil for leak repairs is eliminated
  
• Outages are kept to an absolute minimum
  
• Monthly reports on leaks are eliminated
  
• Action plans to repair leaks are eliminated
  
• Contamination hazards to the environment are eliminated

Circuit Breaker Leak Repair

Leaking SF6 gas can affect personnel, equipment, and the environment. Plus, it’s increasingly expensive to replace. New leak detection technology now enables utilities to survey entire energized substations and pinpoint SF6 gas leaks fast. This new technology can:

• Detect leaks with the equipment still in-service
  
• Quickly pinpoint the source of leaks
  
• Complete survey of an entire operational substation in less than a day
  
• Detect leaks as small as 2lbs/year
  
• Make leak detection less labor intensive and more reliable

Team’s composite material, third-generation circuit breaker repair clamp stops SF6 gas leaks. When you use Team’s composite clamp to stop an SF 6 gas leak, it:

• Eliminates arcing
  
• Eliminates corona action completely
  
• Form fits any configuration
  
• Works on leaking transformers as well as leaking circuit breakers
  
• Applicable to both gas and oil leaks
