Voltage Notching is described by IEEE as a recurring power quality disturbance due to the normal operation of power electronic devices (i.e. rectifier), when current is commutated from one phase to another. Conventionally, the current waveform is used as the starting point for harmonic analysis, and voltage notching is simply derived from the IZ drops of the harmonic currents. In addition, voltage notching characterizes an unusual case that falls between harmonics and transients. This is... (Please Click Link for Full Content and More!)
