Emergent IPB Repairs

Home > Projects > Emergent IPB Repairs


This plant relied on EBI’s emergency response team for expedited tech rep analysis and repair after they experienced excessive damage caused by a grounding failure. Once onsite, EBI collected the information needed to put together a complete refurbishment and repair plan to bring the system back to safe and operatable condition.

Scope of Work:

  • Replaced conductor adapters and 90-degree conductor ends in generator bushing boxes
  • Replaced the A-Phase seal-off between the busing box and the air crossover
  • Replaced the dust caps, reinstalled the upper boot flange, and installed new bellows
  • Cleaned and painted the inside of the bushing boxes
  • Installed new braids, torqued, and DLRO tested
  • Completed an as-left Hi-Pot testing on all 3 phases of the IPB
  • Installed air cooling piping for the generator doghouse
  • Installed new IR windows, provided by the plant on the side of the bushing boxes to view the braid connections
  • Replaced the damaged IR window on the A-Phase access cover
