Switching Surges in Underground Distribution Systems

Field tests, augmented by simulation studies, were performed to:

  1. Characterize voltage transients generated by routine cable and capacitor switching operations.
  2. Compare the performance provided by different switching devices.
  3. Generate guidelines for switching practice and arrester application which can minimize switching surge overvoltages applied to underground distribution systems.
