Electromagnetic Compatibility Diagnostics and Filter Selection
SpareX engineers coordinate technical evaluations of conducted electromagnetic noise across industrial drive systems and automated machinery. We evaluate high frequency ripple and voltage spikes generated by variable frequency drives.
Our team selects factory tesch EMC mains and feedthrough assemblies providing insertion loss up to 100 dB to ensure uninterrupted equipment operation and compliance with international standards.
Enclosure Mounting, Shielding and Grounding Standards
Effective suppression demands low-impedance ground bonding between filter metal housings and control cabinet backplates. We verify enclosure screening and cable separation to eliminate parasitic coupling.
Comprehensive post-installation tests verify proper attenuation levels under real industrial drive loads across single and three-phase power lines.
