The infamous Stuxnet worm made headlines in 2009 when it penetrated Iranian Nuclear Facilities, resulting in the destruction of their centrifuges. The debate regarding the origin of the worm spanned political boundaries, but nonetheless it uncovered the next generation of zero-day attacks that could disrupt industrial processes relying on inter-connected components.
Because of their many benefits, Variable Frequency Drives, or VFDs, are swiftly surfacing in large industrial systems with complex motor systems requirements. The benefits of VFDs include higher system efficiency, operation flexibility, and improved reliability. The key to success behind this adoption of VFDs is developing clear-cut, well-defined requirements for running drives and motors. Having requirements in such a form allows components to be designed in an optimum manner, resulting in highest reliability and lowest cost of ownership.
