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.

Answer Posted / nadir

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.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
