Earthing transformer

When the system neutral may not available, earthing transformer may be used to obtain the neutral. The neutral point of transformer to the earth ground network provides a reference point of zero volts.

This spreadsheet calculates following:

  1. Total capacitive charging current (It).
  2. Neutral earthing transformer secondary current.
  3. Required grounding resistor value at primary side (Rp).
  4. Required resistance value at secondary side (Rsec).
  5. Neutral earthing transformer X/R Ratio
  6. Fault current through neutral – single line to ground fault (If)
  7. Rating of neutral earthing transformer (P).
