The methods of protecting electronics from circuitry failures and managing inrush current at power on has evolved significantly from a simple fuse and maybe a P-channel FET to much more sophisticated ...

Your industrial uninterruptible power supply (UPS) is the foundation of the emergency power system, and it ensures the continual operation of your facility under fault or other abnormal conditions.

To manage the challenges of today’s complex electrical power systems and tightening budgets, facility managers need to understand the critical connection between electrical commissioning and ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

Out-of-step protection is a critical component of modern power system protection schemes—its importance has grown significantly with the increasing penetration of inverter-based resources (IBRs) and ...

One of Demetrios Tziouvaras’ favorite things about his job at SEL University is sharing his knowledge and experience with other engineers who are eager to learn the art and science of power system ...

Most of us in the U.S. take electricity for granted. Nearly every home depends on it for daily life. Yet how safe is our power supply and other critical infrastructure, like phone lines? According to ...
