NGR MONITOR HV LVPS PROFIBUS NC K4. 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.

SE-325NT is a neutral-grounding resistor monitor with a supply voltage of 120 ac and a ground-fault trip level of 0.5–4.0 A.

RS-485 TO RS-232 CONV INDUSTRIAL. Industrial TIA-232/TIA-485 converter converts a TIA-485 signal from an FPS, FPU-32, MPS, or MPU-32 to a TIA-232 signal for a computer or PLC. Industrial network quality.

The SE-134C/SE-135 is a microprocessor-based, combination ground-wire monitor and ground-fault relay for resistance-grounded or solidly grounded systems. It continuously monitors the integrity of the ground conductor to protect portable equipment from hazardous voltages caused by ground faults. The SE-134C/SE-135 is field proven in monitoring trailing cables on large mobile equipment such as drag-lines, mining shovels, shore-to-ship power cables, dock-side cranes, stacker-reclaimers, submersible pumps, and portable conveyors.

NEUTRAL-EARTHING-RES MON PROFIBUS NC-K4. The SE-330AU is an advanced earth-fault and earthing-resistor monitoring relay for low- and medium-voltage transformers and generators. It monitors neutral current, neutral-to-earth voltage, and neutral-to-earth resistance. It provides continuous monitoring of the neutral-to-earth path to verify that the neutral-earthing resistor (NER)is intact. This is of utmost importance—an open NER renders current-sensing earth-fault protection inoperative and could result in a false belief that the system is functioning properly. The SE-330AU earth-fault function complies with AS/NZS 2081.3:2002. For non-AS/NZS 2081 applications, see the SE-330 or SE-330HV. The SE-330AU 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. Earth-fault trip level is adjustable from 0.125 to 5A (EFCT) or 0.75 to 30A (CS30). When set to MEM, the earth-fault trip level is adjustable from 2 to 100percent in 1percent increments of the CT-primary rating. SE-MON330 V3.2 or later is required. 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-330AU to the network using a standard Ethernet patch cable. Use of a crossover cable to connect the SE-330AU 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-330AU does not support the use of DHCP. If the SE-330AU is being set-up for first time, it is recommended to only have one SE-330AU connected to the network to prevent communication errors.

SE-330AU-23-00 is an advanced neutral-earthing resistor monitor with a supply voltage ac of 28–52 and a supply voltage dc of 36–72. Network communications is offered via USB; Ethernet (Dual RJ45).

The SE-105/SE-107 is a combination ground-wire monitor and ground-fault relay for resistance-grounded systems. It continuously monitors the integrity of the ground conductor to protect portable equipment from hazardous voltages caused by ground faults. The SE-105/SE-107 is an excellent choice for trailing cables 5 kV and under in underground mining applications. For higher voltages or long-cable applications, see the SE-134C/SE-135.
