The neutral to earth connection in my industry is showing a zero reading
(shorted). I have a machine which has to be installed where neutral to earth is
not shorted and shows a leak voltage <3 Volts. Please suggest me how it is
possible.

Possibly your machine required an IT wiring which is unearth neutral. Your machine may required only a PE and the PE electrode shall be installed at a distance of 1.5 longer than your transformer/ neutral earth electrode length.
The isolation transformer will also create harmonics and required to dissipate.

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.
