Switching Surges in Underground Distribution Systems
Field tests, augmented by simulation studies, were performed to:
- Characterize voltage transients generated by routine cable and capacitor switching operations.
- Compare the performance provided by different switching devices.
- Generate guidelines for switching practice and arrester application which can minimize switching surge overvoltages applied to underground distribution systems.
