NGR Panel encloses Neutral Grounding Transformer (NGT) and Neutral Grounding Resistor (NGR) for grounding/ earthing of Neutral current during unbalanced three phase load of the generator. This is essentially required for protection of the generator.
Neutral Grounding Transformer (NGT) steps down the voltage of neutral bus from 6.6 KV/ 11 KV/ 15.75 KV level to 110 Volt or 220 Volt level. This stepped down voltage is connected to a netral grounding resistance and a ground earth terminal fro bringing the voltage level of neutral bus as close as possible to zero voltage level
