Power Quality Improvements for an Electrical System with an Automobile Shredder

Abstract

The quality of the power supplied by utilities today is

effectively defined in the harmonic standards adopted

by many countries or by local utility codes. This is

primarily due to user demands for quality power so

that user power interruptions are minimized.

Presented are numerous possible solutions to

address flicker and a case study for an automobile

shredder from the planning stages through

measurements after installation. The solution chosen

for this application will be discussed and presented.

compensator, hybrid VAR compensation, flicker,
