Neutral Earth Voltage Calculator
Estimate resistive neutral voltage drop for an explicitly source-bonded topology.
A QUICK WALKTHROUGH
How to use this tool
- Select a resistance model.
- Enter current and resistance or length with resistance per length; optionally add phase voltage and a measurement.
- Calculate and export the full report.
Formula and scope
V = I × R; length mode uses R = length × resistance per length. Percentage = model voltage / phase voltage × 100. Difference = measured − model. Assumes a neutral-earth bond at the source, negligible earth-conductor drop and a resistive equivalent. Inputs describe the same conductor segment and operating condition.
Limitations
No diagnosis or safety threshold. Harmonics, topology, electrode behaviour and faults cannot be inferred. Network diagnostics require explicit topology and impedance models.
