Best practices for EMC cables and glands used with variable speed drives
Variable speed drives (VSD) are used extensively in modern times, not only for speed control of motors, but also for efficiency. The downside is that the square wave DC output of a VSD causes electromagnetic interference (EMI) to occur. This occurrence can cause electrical and electronic devices nearby to malfunction or fail. Screened cables are […]
