Abstract :
The need and operational criteria for an instrument capable of performing time-domain electrical power analysis are investigated and justified. The instrument is linked to a host personal computer, which performs the signal processing and mathematical analysis. This time-domain correlation technique can be used to analyze the different power components in power networks and calculate the effects of distortion. Effective compensation of polluted power systems can be designed using this instrument. Practical results have shown the excellent online operational characteristics of this measurement system, with excellent accuracy being obtained in both the time and the frequency domains
