Neutral Grounding Resistors

NER Neutral Earthing Resistors Neutral Earthing Resistor, NER, Up To 110KV, 100A/200A/300A/400A, 10 Seconds Faulty Time, IP21-IP54 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

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

Neutral Grounding Resistors, Neutral Earthing Resistors, NGR, NER Neutral Grounding Resistors, also named Neutral Earthing Resistor, It is used to limit the fault current for safety of equipment and personnel in industrial systems. In solid grounding, the system is directly grounded and the fault current is limited only by the soil resistance. The fault current can be very high and can damage the transformers, generators, motors, wiring and other equipments in the system. The

Neutral Earthing Resistor(NER/NGR) is suitable for the operation mode of neutral point grounding through resistance, and is widely used in transformers or generators of 6-66KV AC power grids such as power plant power system, substation power supply system, industrial and mining enterprise power distribution system, etc. on the neutral point.11KV Neutral Earthing Resistor, NER/NGR, IP23 Protection Grade, 10A Faulty Current And 10 Seconds Rated TimeOperation EnvironmentInstalla
