Product Description

Neutral Earthing Resistors, NER, used to limit the fault current for safety of equipment, up to 110KV

Neutral Earthing Resistors (NERs) – sometimes called Neutral Grounding Resistors (NGRs) – are employed in AC distribution networks to limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault.

NERs limit fault currents to a value that does not cause any further damage to switchgear, generators or transformers beyond what has already been caused by the fault itself, and in some cases limit touch and step potentials to safer values than a solidly grounded systems. In addition, consideration is given to operation of protection relays within the required time.

General Features

1.Stainless-steel resistor elements
2. Bolted resistor element connections instead of welded connections providing assemble of spare parts on site immediately
3. High thermal capacity to absorb high currents
4. High altitude ratings
5. Rugged shock-resistant construction
6. Solid top cover sloped to prevent water accumulation

Technical Specifications

1. Operation Voltage : Up to 110 kV line to line systems
2. Rated Current : Up to 5000 A
3. Ambient Temperature : Up to 55℃ (For higher ambient temperature, consult factory)
4. Resistance Alloy : Stainless-steel (CrNi or CrAl)
5. Different Protection Degree according to demand
