It may seem like a long time ago, but with respect to the age of the earth, electricity is in its infancy. When such famous names as Franklin, Edison, Tesla, and Volta were mesmerized by that “blue flame”, who could have imagined the unlimited potential (no pun intended). Electricity is part of everyone’s life and living without it is practically impossible.
The biggest task after the discovery of electricity was developing a way to generate...
Over the last few decades, arc-fl ash hazards have been a significant concern for many electrical workers and employers. Many methods have been developed through the years to assess incident energy.The most common is that of the IEEE 1584, Guide for Performing Arc-Flash Hazard Calculations. These...
Maximizing safety and minimizing downtime BY MAURICE D’MELLO, GE Industrial Solutions A generation ago, an arc flash hazard was an interesting tangent to consider in electrical system design, but not a major topic for discussion. That all changed with the Canadian Standard...
Line-interactive uninterruptible power supply (UPS) systems play a vital role in maintaining seamless operation during power outages. Their integration with backup generators, however, can pose challenges regarding synchronization and power quality. While both UPS systems and generators serve as...
While most discussions about arc flash involve the calculation methods and associated personal protective equipment (PPE), electricians have a number of ways to protect themselves and their gear, including arc-resistant equipment and remote actuation and racking systems that eliminate—rather than...

A common misconception within the electrical industry is that low-voltage systems (typically operating at 600V or lower) pose a lesser arc flash risk than their higher voltage counterparts. While the potential incident energy may be lower in some cases, underestimating the hazards present in...

While the threat of shock and electrocution from inadvertent contact with energized parts has long been recognized, the arc flash and arc blast hazards have only fairly recently been incorporated into the electrical safety standards. The U.S. federal agency the Occupational Safety and Health...
Power system software tools are now being used on a day-to-day basis to analyze arc flash hazards and to find new ways to reduce hazards effectively before people work on energized equipment. Automation within software has allowed quick analysis of complex systems and design of solutions for arc...
