The challenging tasks of keeping the data flowing reliably between the RTU system and the utility enterprise is now being complicated with aging and obsolete infrastructure.
Based on real-world test data and investigation results from on-the-job safety-related incidents, we have found low-voltage arc flash energy can be underestimated. “Low voltage” in the NESC is defined as 50 volts (V) to 600V (ac). Specifically, one area of concern is 480V equipment, because 480V, three-phase related arc flash incidents can have severe consequences.
It’s important for installers and inspectors to fully grasp the scopes of the NESC and NEC, how and where each of them applies and the point of demarcation where one code yields to the other.
Electric utilities face the challenge of managing aging and unsupported legacy automation and monitoring equipment at their substations and pole-tops. This equipment is critical for accessing data from intelligent electronic devices (IEDs) for measurement and protection, automating key functions and enabling remote users to securely control power-system devices.
During a disruption in electrical service, there are various responsibilities that the utility and homeowner have regarding safe delivery of electricity. This sometimes-contentious issue involves a defined term found in Article 100 of the 2017 National Electric Code (NEC) known as the “service point.” Which begs the question, “How well do you know your electrical service point?”
Electrical hazards quickly multiply for workers involved in recovery efforts following weather emergencies, such as downed electrical wires.
The report, Navigating Utility Business Model Reform: A Practical Guide to Regulatory Design, offers a menu of regulatory options for policymakers, utilities, and electric customers to best support and manage the evolution of a 21st-century grid.
Electrical grid infrastructure remains one of the nation’s biggest vulnerabilities. From storm damage, to vandalism, to deliberate attack, members of the professional electrical community, utilities, the media, state leaders, and government agencies need to consider how the United States can most effectively secure the safety, dependability and future of the national electrical grid.
One of the largest power-generating dams on the Columbia River in the northwest United States needed to replace a single-ended unit substation to ensure operational uptime.
Based on consumer demands, electrical manufacturers have developed new permanent outdoor solutions that are safer, more convenient and more reliable than previous outdoor electrical products.
