Preventing induced EMF (electromagnetic interference) from VFD cables in cable trays requires physical separation, proper shielding, and correct grounding practices . VFDs generate high-frequency EMI from fast switching speeds that induces noise into adjacent control and instrumentation cables. Key Prevention Strategies Strategy Implementation Effectiveness Physical Separation Maintain minimum 8-inch (20cm) separation between VFD power cables and control/instrumentation cables Critical Segregation with Metal Barriers Use solid metal divider strips inside same tray (height = side-rail height) OR install dedicated separate trays for VFD power vs control cables High Use Shielded VFD Cable Specify copper tape-shielded VFD cable with XLPE insulation (not unshielded or braided) Essential Ground Shield at Both Ends Terminate VFD cable shield at drive end AND motor end to provide low-impedance path for noise current Critical Bond Cable Trays Ensure all cable...
