Three of the most important tests performed on the busbar are the High Potential or Hipot Test, Partial Discharge Test, and the Insulation resistance test, also known as a Megger Test. Repair / replace damaged components, if any. The support system for the bus bars is complete. If significant arcing occurs regularly, it can greatly accelerate the erosion of the insulation and may lead to inefficient power transfer or total failure of the insulation system. Are any joint packs installed along the slab. Testing also confirms consistency in the outputs of critical manufacturing processes, confirming that there are no defects that affect the part's performance or expected lifespan. The objective of testing is to provide confidence in the real-world performance of a part design.
