Choosing the right filter for an application is considered by many design and electrical engineers to be something of a dark art. Fortunately, help is at hand – a new whitepaper from electromagnetic compatibility (EMC) specialist EMC Standards. The whitepaper provides design engineers with a guide to designing the right filters for their products, and is available for download in the member’s area of the EMC Standards website.

 The whitepaper, by global EMC specialist Keith Armstrong, offers guidance on choosing the correct specifications and style of a filter. Armstrong states that the guidance is akin to taking “anti-Murphy” precautions — referring to the adage that "anything that can go wrong will go wrong". The advice aims to pre-empt Murphy’s Law from affecting filters, through better specification in the design process. 

Correct filter specification is critical in ensuring the rest of the design process is completed with minimal project cost, with the remainder of the process often being a matter of trialling different filters and measuring emissions and/or immunity.

Armstrong also offers a range of tips to help engineers improve the effectiveness of their designs. One such tip is for engineers to understand that filtering and shielding should be designed together, because neither will achieve anything like their full performance, without the other being designed correctly. Another tip is that the full specification of a filter will not be achieved without careful design of its assembly in the product.

“EMC filtering is a gripe of many electrical and electronics design engineers,” explained Keith Armstrong. “This is because it’s difficult to accurately predict the performance a filter will deliver when installed in a product, which means that experimenting with different filters is often necessary. Good initial design and specification ensures that this experimentation stage does not cause unacceptable delays in the product entering the market and does not significantly increase production costs.

“With this whitepaper, engineers can get a greater understanding of the importance of proper filter specification at the right time in the design process. I also provide a brief overview of other factors to consider, such as RF shielding and the often-optimistic impedance specifications of filters, to help ensure safe and reliable products can be designed more quickly and cost-effectively.”

The whitepaper is available for download for members of the EMC Standards website. Engineers interested in accessing the whitepaper and a wealth of other EMC resources and cost-effective courses can do so by registering with EMC Standards.

Unique circumstances sometimes make it challenging, impractical, or even impossible for products to undergo the traditional certification process. This could be due to new technology that does not fit within a current standard, custom or imported equipment or impracticality due to limited volume production runs. Additionally relocating, modifying or refurbishing equipment introduces additional compliance requirements that if ignored can prevent a product from being placed in service.

In these unique situations, contractors and manufacturers of electrical products need to understand the steps to take to avoid having equipment red-tagged and prevented from being connected or installed at the job site. Go HERE to register

One of Canada’s largest wastewater treatment plants at Annacis Island provides secondary treatment to approximately 175 billion litres of wastewater every year for over 1 million residents in 14 municipalities. After almost 20 years in operation, the variable frequency drives supporting the critical pumping systems for the primary treatment and secondary treatment facilities had to be replaced to ensure that the plant’s high operational availability and reliability will not be compromised in serving the plant, the surrounding municipalities and the environment. Metro Vancouver Regional District chose to deploy Rittal’s enclosure and power distribution solutions with E-plan software to efficiently support vital infrastructure improvements by reducing equipment replacement times and thereby minimizing risk to plant operations.

 Littelfuse to Host Webinar on Arc-Flash Protection

 

PBSI Littelfuse logo seminar 400Littelfuse, Inc., a global manufacturer of technologies in circuit protection and power control, invites plant engineers, facility managers, and maintenance professionals to join our special arc-flash webinar on how to cost-effectively protect against catastrophic arc-flash events. The webinar will take place on Tuesday, February 26, 2019 from 1:00 PM to 2:00 PM Central Standard Time.

Attendees will learn:
• Methods available to help identify the risk of arc flash within your system
• How to choose the right arc-flash mitigation solutions to extend the life of your equipment
• Ways to increase working safely beyond the essential Personal Protective Equipment (PPE) suit
• A real-life example of how a few thousand-dollar investment helped a customer avoid an $800,000 catastrophic arc-flash event

The webinar is free, and attendees will have an opportunity to ask questions in a live Q&A session after the presentation. To sign up, visit the arc-flash webinar registration page.

 Like many cyclical industries, mining is reviving, driven by steady global economic growth and an increasing demand for materials to support new technologies like electric vehicles, renewable energy and mobile devices. Despite the optimism, the industry still faces major operational challenges including process efficiencies, cost control, worker health and safety, and skills gaps. To address these challenges, Rockwell Automation introduced The Connected Mine, leveraging the latest enabling and digital technologies.

Utilizing advanced analytics, The Connected Mine helps mining companies collect and aggregate data to gain end-to-end visibility into their operations and make informed business decisions to improve mining operations.

Cybertech developed the Process Control and Safety Instrumented System Auditor to identify high-risk misalignments between plant process control and safety systems – and provide sufficient guidance to each plant system owner to resolve material issues.

Computerized data analytics are effective in mining the big data found in a typical process facility. The Cybertech System Auditor accepts native data from plant systems, cleans up and standardizes the data with purpose-built C# data mining applications and SQL data manipulation. Tiered SQL views minimize data duplication and facilitate automatic updates when base native data changes (e.g. after a system owner advises that they have resolved identified issues).
