From Lab to Field: SXCY Impulse Voltage Generator's Solution for Complex EMI Testing Environments

On-site impulse voltage testing presents significant challenges in complex electromagnetic environments. Interference from inverters, power electronic equipment, and other sources can cause control malfunctions, waveform distortion, and data inaccuracies. The SXCY Impulse Voltage Generator addresses these issues through a systematic, interference-resistant design to ensure reliable on-site testing.

1. Ground Interference: Imperfect grounding systems create ground potential differences, introducing common-mode interference via measurement cables.

2. Conducted Interference: Strong electromagnetic noise couples into control units via power and signal lines, causing false triggering and synchronization failures.

3. Radiated Interference: Electromagnetic fields induce differential-mode interference in test circuits, leading to measurement errors in waveform parameters.

This system attenuates spatial interference by over 30 dB, effectively suppressing common-mode noise.

• Equipment-level metal shielding structure
• Dual-layer shielding for measurement chains
• Optimized single-point grounding scheme

Built-in DSP digital signal processors enable real-time filtering of periodic interference. The system supports background noise self-check functions to ensure the authenticity of measurement data.

This solution has been successfully implemented in substations and manufacturing workshops. Even in complex EMI environments, it delivers pure impulse waveforms compliant with IEC 60060-1 standards, ensuring stable and accurate test results.
