Counterfeiting Kills

Each year, the counterfeiting of well-known brands and products continues to rise, creating an even more threatening problem. Such well-known counterfeited brands, including consumer safety and critical electrical products, are estimated to be five to seven percent of world trade. The International Anti-Counterfeiting Coalition (IACC) estimates that the counterfeiting of distinguished brands costs industries $600 billion each year worldwide and may result in as many as 750,000 lost jobs every year in the United States.

Arc-Flash Hazard Calculations Guide Cover

Calculating Incident Energy

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 equations have remained the same since the standard was first published in 2002. Based on the results of more than 1,800 tests, the 2018 edition of the guide provides new formulas that are both more accurate and more complex. These formulas also take more parameters into account now, including the conductor orientation at...

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.
