Protecting switch contacts when energizing DC contactors Companies often call on Matrix to help solve problems that arise during new installations, normal operations, and/or upgrades. This small case study examines how Matrix engineers helped an energy company investigate the cause of catastrophic damage to switch contacts encountered during an upgrade of their coke and by-products […]

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 […]

Flexibility Key to Speeding the Build of a Duplicate Chemical Plant Many manufacturing facilities have to consider the impact of a natural disaster on their operations—whether tornadoes, hurricanes, earthquakes, floods, or wildfires. And sometimes customers raise concerns about whether their supply source can deliver regardless of what Mother Nature is up to. In 2012, a […]

Understanding and Preventing Fault Masking It’s critical that industrial machinery stops safely when a system fault occurs. However, older safety systems and complex systems with multiple safety switches may be prone to fault masking. Fault masking is a dangerous condition in safety circuits. It results from daisy chaining multiple safety devices in a safety circuit, […]
