    NGR current will flow if the NGR is healthy. systems, the magnitude of charging current can be The SE-330HV will trip on ground fault if fault current conservatively estimated as ½ A per 1,000 kVA on low- exceeds the GF TRIP LEVEL setting for an interval voltage systems and 1 A per 1,000 kVA on medium- equal to the GF TRIP TIME setting.

  • Page 6: Typical Values For Tripping Systems

    The SE-330HV provides the following additional features: • When the trip level is set to MEM, the ground-fault trip setting is defined by an internal non-volatile memory variable. Range is 2 to 100% in 1% increments of the CT-primary rating.

    Non-critical diagnostic codes include SD Card status and USB Error status. All other diagnostic codes are considered critical. Starting with SE-330HV firmware version 2.60 and SE- MON330 software version 3.8, the SE-330HV can be configured to show only critical diagnostic codes. In this configuration, non-critical diagnostic codes will not be indicated with the DIAGNOSTIC LED.

    The accuracy of a typical current sensor decreases below 5% of its current rating. CT-primary current- injection testing is recommended to verify trip levels below CT-primary rating. Section 9.4. Littelfuse Startco current sensors are designed for use at low levels and respond linearly to 2% current rating.

    If the G terminals on the sensing resistor and the SE-330HV are connected to an isolated ground, the SE-330HV will be exposed to the GPR. If the GPR is greater than the terminal-block rating, the SE-330HV must be isolated from station ground and precautions must be taken with the power supply and the trip contacts.
