Written by Fatemeh Dalilian, Manufacturing Engineer Intern I have always been a fan of running a business and managing things since I was a child. Sounds like a boss baby, right? A boss baby I was! One of my childhood dreams was to own a big library because I loved books. At the time, I had many more books than all my friends. So, at the age of eight, I opened my own library! I even had designed membership cards for my friends and had numbered all my books. Of course, all my customers were my close friends and I was not charging anyone for my library membership, but I was enjoying running my little library and that mattered the most to me! Other than having zero revenue, I had a very successful and growing business with happy customers and a big sense of accomplishment !!! Years later, when it came time to choose a career path, it was clear my passion was leading me towards a career where I could optimize, manage, design processes and solve problems. In pursuit of my passion, in the ...

The Occupational Health & Safety Association (OSHA) have reported that arc flashes result in over 7,000 burn injuries per year in the US, with over 400 people dying as a result. That’s an average of 1 to 2 arc-flash related deaths per day , a disturbing statistic. In my last post in this blog series , I discussed the cause of arc fault and arc flash events, the serious risks to electrical safety they pose to people and equipment, and an overview of protection methods. Without any protection, an arc fault can be maintained for a longer time. This, in turn, means that destruction, including electrical fire, will be propagated outside the electrical switchgear. There are many methods to reduce the arc occurrence, reduce its propagation, and mitigate its impact. These solutions can be designed during construction of the switchgear or added later in the retrofit process. Now, let’s look at the two approaches that can be used: active and passive arc protection. Passive arc flash pro...

In the beginning, only fuses were used in electrical distribution systems to protect people and equipment against short circuits, circuit overloads, and other types of faults. Then, circuit breakers were introduced, offering many advantages over fuses. For processing and manufacturing operations, protecting motors is crucial to maintain productivity. As the cost of a fuse is typically much lower than a circuit breaker, fuses have often been the choice for this application. However, circuit breakers have evolved a lot in recent years. Comparing modern circuit breakers to fuses reveals how circuit breakers can help machine manufacturers and facility management teams achieve greater safety and reliability, lower costs, and support for energy management initiatives. 1. Consistent performance One downside of fuses is that their performance can degrade due to aging, even causing them to open during normal conditions. In addition, there is no way to test a fuse, so you will never know the e...
