Power Systems Harmonics: Modeling and Analysis

Electric voltages and currents that can cause power quality issues on an electric power system are called harmonics. It can be produced by electronic devices with nonlinear loads drawing current in sudden short pulses. They are prevalent when multiple computers, printers, fax machines, copiers, UPSs, variable speed drives, etc., are all on the same electrical system. Harmonics specifically lowers the power quality and its efficiency in a commercial building or industrial facility. Overloadi...
