SE-330HV Series - Neutral-Grounding-Resistor Monitor

330hv_PG5_330
Roll Over to Zoom
The SE-330 is an advanced ground-fault and neutral-grounding-resistor monitoring relay. It measures neutral current, neutral-to-ground voltage, and neutral-to-ground resistance. It provides continuous monitoring of the neutral-to-ground path to verify that the neutral-grounding resistor (NGR) is intact. This is of utmost importance—an open NGR renders current-sensing ground-fault protection inoperative and could result in a false belief that the system is functioning properly. The SE-330 can be used with low- and medium-voltage transformers and generators with low- or high-resistance grounding used in processing, manufacturing, chemical, pulp and paper, petroleum, and water-treatment facilities. For high-voltage applications, use the SE-330HV. For applications that require conformance to Australian standard AS/NZS 2081.3:2002, see the SE-330AU.

The SE-330 New Revision provides these additional features:

  • 100 trip records with date and time stamp
  • A mini-USB interface to view measured values, configure settings and check event records using SE-MON330 v3.2 or later
  • An on-board microSD card (included) can be used for long term data logging and firmware upgrades
  • Ground-fault trip level is adjustable from 2 to 100% in 10 discrete settings, and in 1% increments when using the MEM setting and SE-MON330 v3.2 or later
  • Dual Ethernet ports are optionally available with support for fiber and RJ45 interfaces
  • IEC 61850 protocol is optionally available
