NGR MONITOR 48-VDC ETHERNET CE. 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 100percent in 10 discrete settings, and in 1percent 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. COMPUTER TO RELAY CONNECTION: Connect the SE-330 to the network using astandard Ethernet patch cable. Use of a crossover cable to connect the SE-330 directly to the computer running IP-Config is not recommended. A typical router will assign an IP address to all connected computers that are using DHCP. The SE-330 does not support the use of DHCP. If the SE-330 is being set-up for first time, it is recommended to only have one SE-330 connected to the network to prevent communication errors.
