NA60

Grid interconnection protection

The relay type NA60 can be typically used in radial or meshed MV and LV networks as feeder or power transformer protection: on radial, ring and parallel feeders of any length in solidly grounded, ungrounded, Petersen coil and/or resistance grounded systems on parallel connected generators on the same busbar Moreover undervoltage and overvoltage functions are provided as protections or voltage controls. The NA60 relay can be can be shipped with circuits for input phase current suitable for traditional CTs and VTs, or combined ThySensor devices.
