what is neutral grounding resistor?..

Answer / himadri de

Neutral Grounding Resistor (NGR) is simple resistance connected in series between the neutral point of transformer and Earthing pit/point of neutral conductor.
NGR reduce the problems such as insulation breakdown caused by transient over voltage produce by arcing ground fault in underground system and damage to motors and switch gear caused by arcing in solidly grounded system.

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
