HAZARDS AROUND

While working live in the energized grid, presence of voltage around the workers requires special attention. However, live-line (live working) techniques are widely applied for decades, several accidents in the past prove that the level of safety must be improved to minimize the number and seriousness of injuries in the future.
In the high voltage grid, bare-hand method is a common technique for safe live work. In the surroundings of any energized equipment,...

Arc Flash Analysis in DC Power Systems

Advanced approaches to addressing direct-current arcing faults

BY MICHAEL FURTAK & LEW SILECKY, Mersen

Let’s face it: there is not very much information available about direct current (DC) arc flashes. And, if you have searched in vain, well hopefully this feature will give you some insight into arc flash with relevance to DC circuits. Essentially, we want customers to be armed with information so that they can accurately determine the necessary level of protection required when working around these circuits.

In this feature, direct-current arcing fault incident energy calculations are presented to assess the level of risk involved when working...

Compatibility Issues with Generator-Backed Power Systems

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 safeguards against power disruptions, their integration isn't always seamless. Understanding these compatibility concerns is crucial for ensuring reliable backup power and avoiding damage to sensitive equipment.
