There’s a lot of buzz around Industry 4.0 right now, and for good reason. With the goal of creating “smarter” factories where all digital and physical assets are connected using artificial intelligence (AI), the Industrial Internet of Things (IIoT), cloud computing, robotics and other technologies, Industry 4.0 helps create more flexible, responsive and interconnected factories.
Among the intrinsic characteristics of a cable or an electrical conductor, there are two values which are essential for its sizing:
• The maximum temperature of the core in steady-state which allows calculating the ampacity.
• The maximum temperature of the core in short circuit, temperature beyond which the deterioration of the insulation begins.
For standardized cables, these values are imposed by the standard, for example, 90° C and 250° C respectively for cables insulated with EPR/XLPE.
How can innovation processes be transformed to make the best possible use of the Fourth Industrial Revolution’s potential? How can companies identify domain- or technology-specific issues that can be replicated across sites or domains with the objective of revolutionizing whole industries? The author of a new book on tomorrow’s technologies and business strategies explains.
A short-circuit current rating (SCCR) for equipment is required by the National Electrical Code® (NEC®) 409.110(4) and 670.3(A), so understanding how the SCCR of an industrial control panel is determined and what the markings on the product signify will help ensure the safety of the industrial control panel.
According to the market researchers at IDC (International Data Corporation), humans and machines could already be generating 175 zettabytes of data by 2025. If this amount of data were stored on conventional DVDs, it would mean 23 stacks of data discs, each of them reaching up to the moon. The mean 27 percent annual rate of data growth is also placing increasing pressure on the IT infrastructure.
Ground faults are characterized by the accidental connection of a live circuit to a grounded conductor. If the ground connection is solid enough there is a potential for extremely high currents flowing through the live circuits to ground. The current may be high enough to trip any upstream breakers or blow fuses. Tripping breakers or blowing fuses should render the machinery where the ground connection was made safe to personnel.
A short-circuit current rating (SCCR) for equipment is required by NEC® 409.110(4) and 670.3(A). SCCR represents the maximum amount of current that the assembly can safely withstand under short-circuit conditions. Additionally, the following general statement related to SCCR is included in NEC 110.10
It’s usually quite difficult to tell safety-rated components and standard components apart just by their physical appearance. Although they perform similar functions, there are important factors that distinguish them from one another, and these differences are the reason why only safety-rated components are a viable option for use in safety systems.
Plant managers and technicians have their hands full – not only are they responsible for ensuring day-to-day operations are status quo, they are also tasked with helping to increase production and revenue. So when problems come up, as they inevitably do, there’s nothing like knowing you’ve got back-up at the ready, 24-7.
Each component in an industrial control panel must be properly applied for safe and reliable operation. The application requirements for each component are often quite complex and unique to the component, resulting in erroneous interpretation, leading to improper use of the component. We will review some of the most common misapplications of components within the panel. UL 508 switches Listed as a “manual motor controller” are designed to be used for the on/off or manual motor controller function to meet NEC requirements in Article 430, Part VII.
Your control panel plays a huge role in the productivity and efficiency of your operation.Even in rugged environments, your panel should be elegant in its simplicity, clear in its labeling, and compact in space. Here’s how to make sure your control panel doesn’t hinder your efficiency but will maximize your performance… There are some features that all control panels must include. For instance, the incoming power switch should almost always be at the top right corner, which is exactly where your high-voltage components should be as well.
Those of you in the food industry are already familiar with the Food Safety Modernization Act (FSMA)—a law that focuses on preventing contamination, rather than reacting to the problem after the fact. A big part of FSMA compliance has to do with the design of plant equipment, which includes the electrical components that provide power to manufacturing lines.
AB-CO PURGE is a Limited Liability Corporation headquartered in Amherst (Buffalo area), New York. The company manufactures purge and pressurization systems used with electrical enclosures in both classified hazardous locations and non-hazardous locations.
The next industrial revolution is here. New technology and automation solutions are catalysts for evolving your mining operations – helping make you more connected, efficient and productive. In order to optimize mine performance, miners must first be willing to embrace change. Embrace the Internet of Things (IoT).
The three-member team of GSA Elektrotechnik approaches their projects with much enthusiasm and joy. This includes finding and using new products such as the new RiLine Compact that was used for the first time for a heat recovery system.
Control panels present a major opportunity for manufacturers to improve operational efficiency, boost flexibility, reduce engineering costs and save valuable floor space. With this in mind, Omron has developed a unique set of guidelines, known as “Value Design for Panels,” that can help manufacturers create better control panels.
