• Using a Virtual Main to Mitigate Your Arc Flash Hazard

  Using a Virtual Main to Mitigate Your Arc Flash Hazard What Is an Arc Flash? In electrical power systems, unwanted electrical discharge between conductors results in what is called an “arc flash”—the rapid release of energy in the air. These arc flashes release heat that is 35,000°F, creating a major risk of injury for those […]

• How to Handle Harmonics in Electrical Power Systems

  How to Handle Harmonics in Electrical Power Systems While musical harmonics can be pleasing to the ear, electrical current harmonics are an increasing problem in power systems. Equipment and cables can overheat, motors can be damaged, and your electric bill could be a lot higher than it needs to be. Without going into Fourier equations […]
