Abstract: | Computer Loads and systems can be found in all of societyâs industrial, commercial, and residential sectors. The nature of these loads in such that they distort the line-current waveforms and, in some cases, can significantly distort the supply-voltage waveforms causing disruption in computer system performance. The voltage (i.e. line-to-line, line-to-neutral and neutral-to-ground) and the phase current waveform characteristics of many computer loads are similar. This paper will present several case studies to reveal the unique power quality characteristics of several commonly used computer systems (e.g. workstations, heating plant process computers). This paper will also discuss the impact of the computer loads on the supply voltage waveforms. |
