What is Neutral-Earth Voltage Analysis in Servo Motors about?

This report analyzes abnormal Neutral–Earth voltage and leakage current in a 415 V servo motor system, identifying a 22 V voltage and 0.5–0.7 A current during operation. The findings suggest issues related to EMI coupling and potential insulation degradation, with recommendations for corrective actions to ensure compliance with safety standards. Continuous operation of the system is advised against until grounding and insulation integrity are confirmed.
