Reducing Electromagnetic Interference (EMI) in Control Wires: Design Best Practices
Electromagnetic interference (EMI) poses a critical challenge for industrial control systems. Of course, it’s a problem that’s only exacerbated by the increasingly complex electrical environments we often work with in modern facilities and electrical installations. Nevertheless, from utility substations to renewable energy installations, maintaining signal integrity in control cables is essential for reliable operation. Below we discuss proven design techniques for reducing EMI in control wires, including shielding methods, twisting strategies, conductor selection, and ground referencing, along with how Allwire’s custom conduit solutions can provide an additional layer of protection. Naturally, achieving the most effective EMI protection in control cable […]
