Electric utility engineers designing new transmission and distribution (T&D) systems and evaluating existing systems have relied on sophisticated software programs that can simulate transients. Now ...

Regardless of the system architecture, the circuit design, or the power levels involved, transient load current step testing is a critical aspect of power-system design, test, and verification.

The programmable logic controller (PLC) is an important component in most modern automation and process control systems today. It's also susceptible to lightning-induced transients. To verify the ...

The design of a closed-loop switch-mode power supply creates a path between the variable a designer wants to monitor and the control pin of the designer's converter. This control pin can be the peak ...

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 ...
