What’s What: Grounding, Bonding and Earthing

Posted by The nVent ERICO Team on Jun 19, 2018 1:33:46 PM

Grounding and bonding are an integral part of any modern electrical protection system design. An effective, low-imped­ance ground system is the foundation of an electrical system, regardless of structure type. It is crucial to help provide personnel safety, as well as reliable protection for vital equipment, as well as to minimize inter­ruptions of service and costly downtime. Knowing the difference between grounding, bonding and earthing is imperative to properly design and install an electrical grounding system.

But first, let’s define the terms.

  • Ground: A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth.
  • Earth: The conductive mass of the earth, whose electric potential at any point is conventionally taken as equal to zero. In some countries the term "ground" is used instead of "earth."
  • Bond: The permanent joining of metallic parts to form an electrically conductive path that will ensure electrical continuity and the capacity to conduct any current likely to be imposed.

The Science of a Lightning Strike and How to Safeguard Your Facility with a Lightning Protection System

Posted by Martin Havelka on May 22, 2018 8:02:00 AM

Lightning is a random, yet devastating phenomena. Across the U.S., a lightning strikes on average 25 million times per year and occurs at a rate of 100 flashes per second worldwide. And according to the National Weather Service, the average strike has an average magnitude of nearly 30,000 Amps.

While lightning strikes are unpredictable and no location or facility is immune from the threat of a lightning strike, there are ways to reduce the risk or damage. Reducing the risk of damage from a lightning strike, direct or nearby, with the installation of a lightning protection system is not always a part of new construction projects. However, shouldn’t it be?

With modern urban and provincial development, commercial and residential facilities contain valuable digital electronic equipment used for day-to-day work and entertainment functions, meaning large investments are at risk during thunderstorms. A direct lightning strike delivers damaging energy, which even the most robust electrical devices and systems cannot withstand if protection measures are not correctly taken.

Lightning strikes are unpredictable and random events. There is no technology available that can prevent lightning from striking a structure or guarantee 100% protection. Lightning protection is based on statistical probabilities and the risk tolerance of the property owner.

Continue reading below as we uncover the science of a lightning strike, and how you can reduce the likelihood of damage to your facility from lightning.

What is Facility Electrical Protection?

Posted by Chris Barcey on May 8, 2018 8:02:00 AM

Electrical systems are all around us— at work, home, grocery stores, manufacturing plants and more. Our everyday lives depend on these electrical systems performing at their best without interruptions. If the power goes out during a thunderstorm, it can be a nuisance at home without Wi-Fi or power to the refrigerator. However, at a facility that relies on mission-critical equipment, like a hospital or manufacturing plant, even short-term power interruptions can carry large financial costs. Despite electrical designers’ best efforts, electrical ground faults, electrical transients and other disturbances can, and often do, occur in building electrical distribution systems.

The good news is there are ways to reduce the likelihood of this costly damage and operational downtime.

Facility Electrical Protection is an nVent ERICO engineered systems approach to protecting property from lightning damage and other electrical transient events by providing the most innovative system that meets best engineering practices. Electrical problems caused by lightning strikes, ground faults or power surges pose serious threats to buildings and sensitive electronics. It serves three primary functions:

  • Building protection
  • Equipment protection
  • Electrical noise reduction

The cost of property damage resulting from lightning and surge events can be very substantial. Costs include equipment repair/replacement in process material, operational downtime and opportunity costs. Underwriter’s Laboratory (UL) estimates that the cost of structural damage due to lightning exceeds one billion dollars annually, not including the cost of downtime, repairs and loss of business.

3 Products to Consider for Railway Lightning Protection

Posted by Brian Liederbach on Apr 24, 2018 8:06:00 AM

As a result of changing technology, railways are more likely to feel the devastations of a lightning strike than ever. Microprocessor-based equipment has increasingly replaced solid state technology and is highly susceptible to surges. 

Many complications can arise from railway lightning strikes, including: 

  • Safety risks to personnel
  • Damage to critical equipment
  • Data corruption
  • Operational downtime

As the railway industry continues to move toward more advanced products, effective lightning protection mitigation plans are a must to keep trains up and running and reduce lightning-induced transients.

Continue reading to learn three product lines that help minimize the risk of lightning damage to railways.

Why a Proper Grounding System Is the Key to Effective Lightning Protection

Posted by Brian Liederbach on Apr 10, 2018 8:02:00 AM

Lightning currents inherently want to ground—whether the proper systems are in place or not. A lightning strike, which is intercepted by an air terminal, must have its current transferred to the earth safely and seamlessly. 

The grounding system is the integral part of a modern electrical lightning protection system that must be dependable for this process. 

Without an effective grounding system in place, dangerous ground faults, side flashes and electronic noise can occur, causing damage to structures, fires or personal injury.

Combat Copper Theft: How to Protect Your Investment

Posted by Rohit Narayan on Mar 27, 2018 8:03:00 AM

Copper is viewed as the global standard for electrical conductivity in the utility sector. It’s high current carrying capacity coupled with its resistance to scratches and breakage, and its resilience to corrosion makes it a universal metal for many applications.

As international construction booms and copper demand rises with it, we’re faced with a startling reality: copper theft costs U.S. businesses nearly $1 billion in losses annually.

There’s no sign of slowing in the global construction sector, and that means the threat of copper theft is greater than ever before. Read on to learn the issues surrounding copper theft and how to prevent it from happening to your business.

The Six Point Plan to Achieving Telecom Facility Lightning Protection

Posted by Rohit Narayan on Mar 13, 2018 8:01:00 AM

Lightning is a constant risk. A single direct strike can result in physical damage to buildings and cause catastrophic failure of sensitive electronic equipment. Lightning causes 22,600 fires per year and is the number one natural cause of system failures. As a result, these problems can result in substantial revenue losses.

Telecommunications facilities are particularly at risk of direct lightning strikes—and the electrical surges that ensue—due to their tall stature and complex electrical makeup. 

However, there is a way for engineers to protect telecommunication facilities from the devastating and lasting effects of lightning damage. 

According to Above Ground Level Magazine, engineers can help protect telecom facilities from the dangers associated with lightning strikes using a six point plan of protection. Continue reading below to learn more about these six steps of lightning protection for telecom facilities.

How to Gain Faster, More Reliable Railway Connections with ERICO CADWELD PLUS

Posted by Didier Quoy on Feb 27, 2018 8:03:00 AM

Travel delays are frustrating. On the consumer side, delays cause late days to work or missed flights. For engineers, travel delays mean low customer satisfaction, unexpected downtime and emergency repairs. Everyone has experienced a delay one way or another—especially when they travel via train.

In the state of New York alone, an estimated 1.8 billion people took the Metropolitan Transportation Authority last year. And in the single month of January, there were a total of 60,000 weekday subway delays, with 2,644 delays caused by faulty equipment.

What causes these delays? A main cause of railway delays is due to poor or faulty connections. Below we explain some common railway issues, and how you can correct them to avoid system downtime using the fastest, most reliable railway connections.
