Harmonics are periodic distortions of voltage, present, or power sine waves. Harmonics in power distribution systems are sometimes attributable to non-linear hundreds such as switched method dc electrical power provides and adjustable pace motor drives.Other variables, like line outages and sags or even the starting and halting of a motor, also can
