The SE-330 is an advanced ground-fault and neutral-grounding resistor 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 ...

The NGRM-ENC is a compact non-metallic NEMA-4X enclosure housing an SE-325 or SE-330 Neutral-Grounding-Resistor (NGR) Monitor pre-wired to terminal blocks for easy field installation. Optional features include a fused 600/480:120 V control power transformer and internal/external 3-phase voltage-indicator lights. For SE-330 models, a USB connector is included and additional options include an ...

The PGR-5330 is an advanced ground-fault and resistor monitoring relay. The PGR-5330 measures neutral current, neutral-to-ground voltage and neutral resistance. It provides continuous monitoring of the neutral-to-ground path to ensure the neutral-grounding resistor (NGR) is intact. This is of utmost importance on resistance-grounded systems because NGR failure renders current-sensing ground-fault ...

The PGM-8325 Neutral Grounding Monitor is used on resistance-grounded systems up to 25 kVac to monitor the integrity of the neutral-to-ground path. It measures current and voltage in a transformer or generator neutral-to-ground connection and continuity of the neutral-grounding resistor (NGR). The PGM-8325 coordinates these three measurements to detect a loose connection, corrosion, ground-fault, ...
Manufactured by:Littelfuse, Inc. based inChicago, ILLINOIS (USA)
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 ...

Automatically disconnects non-critical loads from a battery when the battery voltage falls below a predefined threshold. Automatically reconnects the loads to the battery when it is being charged which prolongs battery life by preventing premature damage. No more stranded vehicles! Avoid the time and expense of getting your vehicles towed. The SureStart LVD ensures that there is enough power to ...

High-resistance grounding prevents many of the problems that are associated with ungrounded and solidly grounded electrical distribution and utilization systems. High-resistance grounding can limit point-of-fault damage, eliminate transient overvoltages, reduce the arc-flash hazards, limit voltage exposure to personnel, and provide adequate tripping levels for selective current-based ground-fault ...
