Product Details
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.
