Basics of how to minimize harmonics

The August 14, 2003 blackout emphasized that power quality should not be taken lightly. The blackout was caused by, and affected the power grid — our nation's electrical infrastructure. The issues raised by this event should and will come under scrutiny. Just as the nation looks at its power quality issues, plant engineers must look at power quality issues inside the plant.

Basics of low-voltage circuit breakers

A circuit breaker is designed to keep an undesirably large amount of current, voltage, or power out of a given part of an electrical circuit. Industrial circuit breaker categories tend to follow voltage classes, which are divided according to magnitude. The IEEE divides voltage systems into four classes listed in the table titled "IEEE voltage classifications.
