Input voltage waveform distortion

A numerical value that indicates the accuracy (quality) of commercial power supply. Commercial power is normally a sine wave, but voltage distortion may occur when high-frequency components are added due to noise caused by surges and other factors. In electrical and electronic equipment that requires high input voltage accuracy, significant distortion may prevent normal operation, so caution is required. As a countermeasure, a noise filter that supports voltage waveform distortion may be inserted.
