For the design of reliable power grounding systems for critical electrical infrastructure, soil resistivity investigation is crucial. However, soil resistivity depends on various geotechnical ...

It's no secret that grounding and bonding content continues to resonate with EC&M readers. From NEC Consultant Mike Holt's recent 12-part series on the differences between bonding and grounding to ...

Most utility companies do an excellent job of using equipotential bonding to protect lineworkers who are working aloft. Historically, they've been less diligent about implementing up-to-date ...

Rapid and repeatable information on the long-term performance of emerging substation sensor technologies and substation apparatus under realistic operating scenarios is needed prior to widescale ...

Drive along nearly any major road in the United States and it won’t be long before you see evidence of the electrical grid. Whether it’s wooden poles strung along the right of way or a line of ...

In Episode 34 of EC&M Tech Talk, Electrical Trainer Randy Barnett covers three main points when it comes to earth resistance, also known as ground resistance. First, the National Electrical Code in ...

The utility Eversource broke ground Tuesday on what it called the country’s first fully-underground electrical substation. The 35,000-square-foot facility is part of a larger $1.8 billion energy ...

Electrical substations utilize direct lightning stroke shielding to help ensure proper operation, and to prevent costly damages and extended outages. While modern substation designs and equipment make ...

The study shows that a combination of water content, plasticity index, and dry density, can provide a reliable prediction model for soil resistivity, paving the way for the cost-effective design of ...
