Overview about the most important main distortions








The figures show the most important mains distortions which occur individually or in combination.
From top–left to right bottom:

Asymmetrical clipping sine wave
Symmetrical clipping sine wave [nearly like a retangulr waveform]
Drop out, partly or as a whole, short time for one period
Drop out, partly or as a whole, short time for more than one period
Overvoltage
Undervoltage
Harmonic distortions
Distortion of a half period
DC Offset
Voltage drop, regular or irregular
Variation of main frequency
High frequency [RF–] distortions up to 30MHz... 100MHz
Short time drop outs
Non–regular high frequency distortions [noise, spikes, burst]
