NA30
Grid interconnection protection
The relay type NA30 is typically used in radial MV networks as feeder or power transformer protection: on long radial feeders in ungrounded or Petersen coil and/or high resistance grounded systems on the LV side of parallel connected transformers with any grounding as earth fault protection of parallel connected generators or generator-transformer unit on the same busbar The relay complies with CEI-016 requirements.
