Mission: Critical - The pros and cons of diesel rotary versus static systems

Mission critical facilities are broadly defined as containing any operation that, if interrupted, will cause a negative impact on business activities, ranging from losing revenue to jeopardizing legal conformity to (in extreme cases) loss of life. Data centers, call centers, hospitals,...

Electrical Connectors for Overhead Lines

Utility distribution systems utilize a variety of connectors to join and attach overhead conductors. These components are simple and relatively inexpensive; however, due to their critical function and the large number of components utilized in the electrical system, they deserve some consideration...

Fiberglass Reinforced Polymer Crossarms 5th Percentile Design Strength Value Development

Introduction In 2007, the National Electric Safety Code (NESC) standards committee adopted composite poles, crossarms, and braces into the code. This action was significant in mandating the composite electrical structures manufacturing industry to publish their design strength values to a 5% Lower...

Lateral Fuses and Reliability

Improving protection and control for distribution systems BY STEVE GREEY, S&C Electric In 2008, Toronto Hydro completed a study of its worst performing feeders (distribution system feeder lines). This study identified the utility’s distribution feeders with the poorest reliability. The study...

Transmission Line Resiliency

Resiliency is a term used more and more by transmission line stakeholders including designers, operators, and owners. Resilience is simply defined as toughness or the capacity to recover quickly from difficulties. It can be used to describe a system, an object or even a person. Dr. Ginsburg, child...

Rugged Tablets for Utility Fleet Vehicles

In reports analyzing the response of power utilities to incidents such as Hurricane Sandy, or the more recent ice storms on the east coast, one item has been remarkably consistent—the conclusion that communication requires improvements. The concern is not hard to fathom. Knowing accurately when...

Q&A: Transmission Line Inspection Using Robotics

A: Hydro-Québec’s power transmission system, the most extensive in North America, covers close to 34,000 km. Similar to many power utilities, we need thorough infrastructure inspections to ensure system reliability, availability, and performance.Therefore, we have, developed robotic tools to work in places that are often hard to get to and to provide operators with diagnostic tools to assist them in their decision-making. Hydro-Québec has developed a robot, named LineScout, to inspect live transmission...
