Power supplies: just another detail?

Careful specification can prevent startup problems and maintenance headaches.

Power Supplies

As a chemical engineer by training, one aspect of automation that I had to pick up post-graduation was a basic understanding of electrical engineering. Although it wasn't a natural fit for me (my alma mater makes Chem Es take an electrical engineering course and the EEs a thermodynamics course to separate the wheat from the chaff), I managed to get by, but not without learning a few lessons the hard way. One of the more challenging electrical problems I faced was with the power supply for a continuous emission monitoring (CEM) analyzer system installed at the 200 foot level of a main stack. Fortunately, we had an elevator, and the stack itself was a 26-foot-diameter pipe…

Cybersecurity of nuclear reactors

The potential for remotely turning reactors into weapons is independent of their country of origin.

Q: Thanks for your answer concerning nuclear reactor hacking through the Internet. I would also like to learn if total cyber safety can be guaranteed by eliminating all connections to the Internet or any other network? Can they still be attacked? Also, what is your view of the safety (regular and…

  • 2017 State of Technology: Workstations and enclosures

    They look simple, but paying attention to the details of designing and specifying plant-floor enclosures for workstations, controllers, input/output (I/O) systems and instruments can pay off handsomely in lower initial, operating and maintenance costs while improving operator efficiency and…

  • Breaking the interoperability barrier

    By Jim Montague

    We all knew this was coming—even if it took a few decades. Change can be denied and resisted for a long time, but eventually pressure builds, tectonic plates slip, volcanoes erupt, ice shelves crack, and suddenly the world is different. In the process industries, end users face many similar…

  • Intelligent Project Delivery: Only the Beginning

    The process industries’ push to streamline the execution of capital projects is easy to grasp. Production assets have never been larger, more complex—or more expensive to build. Meanwhile, windows of opportunity open and close seemingly at a moment’s notice. And with some capital projects…

  • Accelerate Engineering Workflows

    Moving automation off the critical path of project execution requires agility as well as speed. As discussed earlier in this article series, the move to configurable single-channel input/output (I/O) systems and fully digital instrument communications has advanced both causes. First, by improving…
