The 2 Most Important Factors to Weigh When Selecting Ground Rod Material

Posted by The nVent ERICO Team on Oct 30, 2018 8:02:00 AM

The purpose of a grounding system is to protect people, structures and equipment, and to ensure maximum safety from electrical system faults and lightning. A vital piece of the system is the ground electrode. The overall system’s reliability is dependent on this component.

When using a ground rod for the ground electrode, the general performance or conductivity of available materials is minimal, but the service life of each material can vary by decades.

The Difference Between Lightning Protection and Surge Protection

Posted by The nVent ERICO Team on Oct 16, 2018 8:02:00 AM

Lightning is known to be the most significant source of surges—bolts have been recorded to have a million to a billion volts and between 10,000 to 200,000 amps. However, lightning only makes up a portion of all transient events in a facility.

Because transients can originate from both external sources (like lightning) and internal sources, facilities ought to have both a lightning protection system and surge protection installed.

This begs the question: what is the difference between these two systems, and how do they work together?

The Pros and Cons of 4 Common Ground Rod Materials

Posted by The nVent ERICO Team on Sep 18, 2018 8:02:00 AM

When it comes to selecting a ground rod, engineers must avoid a one-size-fits-all approach. Different factors—material, soil resistivity, location, facility type, size, among others—play into the overall efficiency and service life of both the ground rod and overall grounding system.

Below we provide key considerations for ground material selection and then compare the most common types.

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.
