3 Reasons Engineers Should Choose Copper-Bonded Ground Rods

Posted by Rohit Narayan on Jan 16, 2018 8:04:00 AM

Picture yourself driving your car on the highway when all the of the sudden you see brake lights and are forced to slow down because of construction. As you come to a stop, you see workers repaving a damaged road. Now, cars begin to line up in front of you and behind you. Where do you go? Nowhere—you’re stuck.

A ground rod, also known as an electrode, is similar to this highway scenario. It acts as the only electrical path to dissipate static discharge voltage (such as lightning) into the earth. When that path starts to break down, the static discharge has nowhere to go and puts the whole system at risk.

Many times, engineers are given the choice between three types of ground rods: copper-bonded steel, copper clad ground rods or galvanized steel for grounding systems. However, one material reigns supreme when it comes to strength, service life and overall investment. Hint: it’s copper bonded steel. 

Continue reading below to learn why copper is the better choice for grounding systems versus it’s steel alternative.

3 Considerations to Maximize Grounding System Life

Posted by Andrew Ritosa on Dec 12, 2017 8:02:00 AM

While there’s no known solution to completely protect your facility from naturally occurring environmental threats, certain steps can be taken to minimize risk. These precautionary steps to total facility protection include the following concepts:

  • Direct strike protection
  • Grounding and bonding systems
  • Transient surge and over-voltage protection

To maximize both the effectiveness and service life of a grounding system, careful considerations must be followed. Read below to learn three considerations to keep in mind when installing your next grounding system.

5 of the Most Common Electrical Grounding Mistakes You Can Make

Posted by Greg Martinjak on Sep 5, 2017 8:04:00 AM

Your facility, technology and other key assets are at risk to lightning strikes. While an effective air termination device and above ground lightning protection system is critical to effective protection, proper grounding can keep people and products out of harm’s way. 

Preventable mistakes in the electrical grounding system can leave it vulnerable to ground faults, side flashes and electronic noise, any of which could result in fire, damage to structures and personal injury. 

Below we outline 5 common mistakes made when designing and installing a grounding system.

How Grounding System Helped Gold Mine Overcome Rocky Soil Conditions

Posted by Martin Havelka on Jun 27, 2017 8:08:00 AM

The Peak Gold Mine, located in New South Wales, Australia, provided gold deposits and copper concentrate throughout the Asian Market from 1896 to 1920.

While the Peak Gold Mine concluded production long before the change of the millennium, production resurfaced at the mine in the mid 2000s, thanks to the discovery of additional gold.

Despite challenging ground conditions, miners at the Peak Gold Mine have uncovered 99,072 ounces of gold, along with 9,070 tons of copper, and have a predicted working life through 2020. 

So how was this massive amount of materials unearthed from a century-old mine? Continue reading to learn how ERICO Ground Enhancement Material (GEM) improved the grounding system and power quality at Peak Gold Mine.
