Used when replacing an Atkinson Omser II with an SE-130-Series Monitor.

NGR MONITOR HV 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-330AU-00-01 is an advanced neutral-earthing resistor monitor with a supply voltage ac of 65–265 and a supply voltage dc of 85–275. Network communications is offered via USB.

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.

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.

3 CHANNEL GF-GC MONITOR ETHERNET. The SE-145 is a three-channel, 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 wire to protect portable equipment from hazardous voltages caused by ground faults. The SE-145 is designed for use on three-way splitter box applications. COMPUTER TO RELAY CONNECTION: Connect the SE-145 to the network using a standard Ethernet patch cable. Use of a crossover cable to connect the SE-145 directly to the computer running SE-MON-GFGC is not recommended. A typical router will assign an IP address to all connected computers that are using DHCP. The SE-145 does not support the use of DHCP. If the SE-145 is being set-up for first time, it is recommended to only have one SE-145 connected to the network to prevent communication errors.

SE-330AU-03-01 is an advanced neutral-earthing resistor monitor with a supply voltage ac of 65–265 and a supply voltage dc of 85–275. Network communications is offered via USB; Ethernet (Dual RJ45).

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

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

SE-325E is a neutral-grounding resistor monitor with a supply voltage of 240 ac and a ground-fault trip level of 0.5–4.0 A.

T3000 Frequency Relay. 120/127V. The T3000 is intended for effective frequency surveillance on generators, busbar or other distribution systems. The relay contains the functions “under frequency” and “over frequency” time delayed, and 2 individual output relays, one relay for each function.

Overload Relay. 230V L-N 5A. The T2700 Overload Relay will protect the generator from excessive active load. The T2700 is necessary to protect the prime mover and alternator against physical damage. The T2700 measures the current through an external 5A CT attached on phase L1. The phase angle (phi) is determined from the voltage measurement across L1 and L2. The T2700 calculates the active current as I x cos phi. If the active current exceeds the preset level (0.02 – 2 x I), the pick-up LED will ignite and the trip delay timer (0.1 – 10 seconds) will activate. The built-in trip relay will energize after the delay has passed, provided that the preset trip level was continuously exceeded during the time of the delay. Dials on the front facia provide easy adjustment of both trip level and delay. The LED based pick-up indication is ideal for testing the unit. Simplicity is the key to trouble free installation and service, as simplicity plays a key role in reducing the Total Cost of Ownership (TCO) for the complete supply system.
