Additional Description: LTFS-SE-330-03-00 NEUTRAL-GROUNDING-RESISTOR MONITOR ETHER
Catalog Description: The SE-330 is an advanced ground-fault and neutral-groundingresistor monitoring relay that is compliant with Rule10-302 of the 2018 Canadian Electrical Code Part I (CE Code). 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 and that it has not been bypassed or shorted. An open NGR renders currentsensing ground-fault protection inoperative and could result in a false belief that the system is functioning properly. A shorted NGR results in higher-than-expected ground-fault current. 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 standards, use the

On-Board microSD CardSE-330-03-00 Item Features
- Continuous NGR monitoring detects resistor failure within seconds, reduces transient overvoltage risk, removes risk of ground fault detection failure
- Ground fault detection main or backup protection to detect a ground fault anywhere on the monitored system
- Adjustable pickup (2 to 100%) selects greatest sensitivity without false operation, adjustable in 1% increments (MEM setting)
- Adjustable trip delay allows quick protection and system coordination
- Universal CT compatibility allows the use of a CT that gives required ground fault settings
- Selectable fail safe or non-fail safe operating modes allows connection to shunt or undervoltage breaker coil or alarm circuit (trip, ground fault, resistor fault relays)
- Trip records onboard 100 event (with date and time) recorder helps with system diagnostics
- Harmonic filtering (DFT) eliminates false trips due to harmonic noise from ASDs
- Local communications mini USB port to view measured values, configure settings and check event records
- Onboard microSD card can be used for long term data logging
- Selectable latching or auto reset operation
- Unit healthy output verifies SE-330 is operating correctly
- Internal circuits are conformally coated to protect against corrosion and moisture
- Normally open K4 unit healthy contact
- Dual RJ45 ethernet communications
