Many existing variable frequency drive (VFD) installations are using wrong cables. Often, interlocked armor TECK or continuously welded and corrugated aluminum armor (CCA) cable are used to connect the VFD to the motor. These cable types will release excessive electrical noise in many installations - and this electrical noise can wreak havoc with the sensitive electronic components, network cabling and other sensitive wiring found in most modern industrial facilities

The solution is to use specially-designed VFD cable with a foil braid or copper tape shield and suitable ground wires. For larger cables it becomes important to use a symmetric ground design to balance the induced ground currents. Compared to TECK or CCA, this type of VFD cable provides superior performance in terms of common mode current (CMC) containment, and in other areas.

We are launching a series of workshops to help companies design, secure and implement industrial Ethernet infrastructure based on today’s proven results.

Evolving Your Networks: A Practical Industrial Ethernet Design Workshops feature customized content delivered by local experts within a brief two-hour session. Our goal is to offer mainstream best practices and simple, common examples, all tied to a step-by-step approach, so attendees leave with a roadmap of exact next steps to take in order to kick-start or improve their network’s infrastructure.

Last month, in Part 1 of this topic, we discussed how applying industrial Ethernet can truly transform your facility and provide unanticipated benefits.

Wireless technologies are thriving on the plant floor for a number of reasons, but two key criteria include improved safety and security and lower costs. Security concerns initially associated with wireless have been dispelled or at least diminished. Standards development for wireless systems has caught up with conventional Ethernet with the development and expansion of IEEE 802.11. The standard governs wireless LAN communications and has helped advance the security of Ethernet wireless systems, some say even beyond that of hard-wired systems. New products such as the BAT300-Rail series with three transmission/reception antennas are now better able to receive signals being sent over the industrial network.

In Part 1 of "Substation Security with Strategic Zones of Protection," we introduced the idea that an Ethernet-based Zones of Security strategy can offer a security umbrella for your substation. But, Ethernet also provides the flexibility and rich supporting protocols and applications that enable a utility to create the powerful Zones of Protection for both physical and cyber assets. Ethernet offers several other critical advantages for substations:

Smart grids collect a wealth of intelligence, beginning at the edge with Intelligent Electronic Devices (IEDs) that collect valuable information such as fault location, relay targets and customer usage in increasingly fine granularity which then is transmitted to the central control area to support the smart grid. Protective relays, meters, remote terminal units, LTC/regulator controllers, and predictive maintenance equipment also are becoming rich sources of data that can be made readily available to remote users. This new information requires increased communications bandwidth and a secure strategy for transporting the information to its destination points throughout the utility.

As power utility stakeholders address the challenges of creating end-to-end security for their smart grids, operations groups can benefit from a “Zones of Protection” strategy protection relay engineers have employed for some time to keep utility grids and equipment safe from fault and system unbalances.

Do you believe that all networking cables are equal?

If you're a regular visitor to this blog, your answer is certainly "No."

In particular, harsh environments require that networking cables be built to meet the environmental challenges in order to insure signal transmission quality. Environmental hazards include EMI, chemicals, water, crushing, flex and temperature extremes.

So what should you look for in a cable to stand up to these hazards?

Frank Koditek, our product line manager – industrial cables, will present exactly what you should look for in the upcoming Cabling Installation & Maintenance Magazine Webinar: Cabling for Industrial and Other Harsh Environments.

If you’d like to learn more about industrial wireless, two great resources are now available. The first is the June issue of Control Engineering, which features a cover story on Industrial Wireless. The cover photo and lead story feature Hirschmann industrial wireless products implemented at the PEMEX Tula Refinery in Mexico.

In this application, the refinery was able to increase efficiency and protect its critical cooling tower s with wireless monitoring and analysis of process and vibration sensor data. Belden and RYMSA, the system integrator, were able to implement the wireless products to protect critical assets and overcome serious line-of-sight issues.

To read more, visit the Control Engineering cover story online--beginning on page 30.

Still haven’t gotten enough industrial wireless?

Last month, Belden sponsored and presented in the successful webinar, “Industrial Wireless: Where and When.”

You can still register to catch the webinar that had over 500 viewers.

This blog post was contributed by Mary Peters, a marketing intern for our industrial networking solutions division.

Did you know that almost every plant floor today has Ethernet incorporated in their infrastructure on some level? In fact, Ethernet is fast approaching becoming the principal infrastructure for industrial automation and control applications.

Applying industrial Ethernet to your infrastructure in a way that fits your application, including utilizing wireless appropriately, can truly transform your facility and provide unanticipated benefits.
